Yoona listened to Sooyoung's story thoroughly, bit by bit, compassion to Siwon started to grew in her heart. She didn't knew he had experienced such a hard, unbelievably cruel life when he has no single idea about his parents meddled in such organization. Yoona could understand now why Siwon refused to get any help from anyone else and be indebted to someone, he had gone through such life alone, only with Sooyoung helping from his back.  Maybe because if he grew close to someone else, he would suffer another terrible loss of someone he hold dear.

---FLASHBACK--- 

Once the assasination and assault in my house ended, the two of us, Siwon and I, decided to go to the place where Seung Won promised us peace in our life, the man who killed my parents and destroyed our family, promised us peace, i was still a child, but I knew myself this : This man would never be a reason of the peace in our life.

On our way to follow after where Seung Won's going, I couldn't help but to release tears and leaned on Siwon Oppa, sometimes I looked at his messy state, but his answer to my glance is always the same, everything's going to be okay, and he kept repeating those words on my ears while looking to my eyes, trying to assure me that everything's under control, though I could tell that Siwon himself didn't know where his decision will brought him.

And half of my journey was filled with deep sadness upon the lost of my mother and father, as I stared at the window blankly, I was projecting their faces on the car's window while they're looking at me, smiling at me, but now they're gone, and no one, even Siwon, could ever bring them back. When I thought of it now, Siwon's decision was merely to protect me from harm, so I didn't end up like our parents, he didn't even think about our house, our education or our future, it was all about me, that's all.

Around an hour, we've reached our destination, when I got off from the car, I saw a large, stand-alone building in front of me, as I glimpsed at the entrance, there were two scary men guarding the door, with similar figures of Seung Won's men who broke into our house. Then I realized, it was Seung Won's organization headquarters, and this is the place where I called a living hell.

The three of us approached the entrance of the headquarters, when the guards saw Seung Won's face, suddenly they bowed ninety degrees, while greeting him a warm welcome. 

"Welcome back, Seung Won, sire!" they greeted with a great volume.

"At ease." Seung Won commanded, the two guards fixed to their previus position. One of them, glanced at us with a strange stare, maybe they're not used to see their leader bringing two kids around to their place.

"Sir, they are.." Seung Won gave the guard who was about to ask, his palm to the guard's face, asking him to not question further about our identity, it seemed like he really intended to kept our identity a secret, but I was sure it was not for our safety, but more to his own.

"Save your question, you have the right to remain silent." he commanded once more, the guard gulped his saliva and straightened his position, afraid of the concequences if he asked furthermore about us. 

Seung Won walked through the door and entered the bulding, inside, we saw terrible views, bunch of peole gambled, women with their minimum clothings played with some men in suits, a man with bulky figure tatooing his own body and many, many things that were unbearable to watch. I closed my eyes and sinked myself on Siwon's embrace, the noise was driving me nuts. Siwon covered my ears, althoguh for him, this was his first time too he saw something so inhuman, and it was really bad timing for him.

However, Seung noticed our afraidness upon the terrible view we saw, all he did was smirking at us wickedly. "Welcome to the real world, son."

I glanced at Siwon for a moment, he was snarling at Seung Won who was turning his back on us, how resentful he was to him, I couldn't imagine what's on his head.

Step by step, finally we released ourself from the crowd of evil beings and arrived in front of an elevator. Seung Won pushed the 'up' button. A sound of dinging elevator was audible after we waited for a minute or two, the three of us entered the elevator, and Seung Won pushed the highest floor, the fifth floor.

Once we reached our destination, we walked out from the elevator, the fifth floor was really different from the ground floor which is full of noises and a lot of people, the fifth floor was neat, and there were rarely humans there, and it was a very quiet atmosphere. Two or three people stared at us with a wondrous look, but they didn't ask anything about us like the guard did. We strolled while ignoring the people who stared at us, and we stopped in front of a room, a room with two large doors, the door has a weird wooden pattern.

Seung Won knocked on the door lightly and greeted the person inside the room. "Seonsaengnim, it's Seung Won, Ruby Division Leader." 

"Come in." the person inside welcomed Seung Won. Then, the three of us entered the room.

Inside, we found a man in suit, who 's wearing a glasses and neatly dressed, like a director, sitting on a working desk while folding his hands, there was a black latop beside him, I figured before we went to the room, he was workingon something with that laptop. The man also looked at us with a strange stare, but he only did it for a brief moment, after seconds passed, he seemed like getting an idea of who we are, even though Seung Won didn't say a word about us.

"Seongsaengnim, I hereby to tell you that I've finished the organization's traitor Choi Ki Ho. Every evidence connected to him, including files he's been working on will be banished soon. That's all I have to say." Siwon gritted his teeth upon hearing Seung Won's painful report to his master, of course, he did it like we weren't there. Siwon gripped my shoulder harder from, but I manage to hold his temper by gripping his hand firmly, finally he let go of his emotion when he remembered I was there, too.

"Arraso, good work. And their family?" the man asked, while catching a glimpse over us.

"We killed them all, sir. There's no one left at that house. Our organization's identity is safe and sound, sir." Seung Won glanced at Siwon, trying to communicate with him through their eye contact, telling him to convince that he's no one related to the guy he just killed. Siwon had no choice but to follow after, and he kept silent. 

"Arraso arraso, very well then, and when will you plan to introduce me to those kids?" the man questioned. Seung Won was a little bit startled, he didn''t expect that his master would notice us, but he has been examining us since we entered his room.

Seung Won pushed the two of us closer to the man, we met his eyes and gulped, somehow his stare and his smile made us uncomfortable with him already. "This..is Siwon and Sooyoung, they are siblings I found in orphanage during my mission to take out Choi Ki Ho's life, this one," Seung Won patted Siwon's shoulder. "This one's got real talent, Seonsaengnim. I'm pretty sure he would make a wonderful asset to the organization. Please let them stay here and let me train him, and if you be so kind please accept his little sister too, she has nowhere to go without her brother." Seung Won begged deliberately, to make his plan succeed.

The man smiled at us, and he placed his hands on our heads. "Sure, why not? You're welcome here, children, please use this building as much as you want to, this place is your new home now." he said kindly, all the worries in our heart vanished in an instant, our fear of being expelled after he figured out who we are left our heart. I smiled at him with a wide smile, I thought this man was not as bad as I thought he would be.

But Siwon was still glaring at him with an intense look, maybe he was still suspicious of this man's identity.

"Seung Won, if you don't mind, will you be so kind to leave the three of us for a minute or two?  I want to know better about this children, privately." he winked at us playfully. "Do you mind?" Seung Won nodded in agreement, and he saw himself out of his master's room.  This Seonsaengnim still smiled to the door's direction when sending Seung Won out, but when his disciple closed the door to the outside, his smile faded, turned into a faint smirk while looking at us.

"So your names are...Siwon and Sooyoung, huh? I'm really glad to see you kids willingly followed Seung Won, he must have scared you with his silly threats to save himself, yes?" Siwon and I looked at each other, we put a puzzled stare, why did this man figure out the method how Seung Won brought us here, even though he wasn't present when the incident on Choi Ki Ho's house happened. Then, we put up a conclusion, that this guy is dangerous. But when we were thinking about running for our lives, he added up his sentence. "Or should I call you...Choi Siwon and Choi Sooyoung?"

Both of our bodies jolted in shock, we gulped our saliva in fear. Who knows what this man would do if he leaked out our identities. The man examined our next moves as we stepped back closer to the exit, he managed to stop us from going by his words. "How do you plan to escape from here when you have Seung Won outside and the rest of the organization to put a stop on you? If I were you, I would reconsider your intention." he said confidently.

Siwon stopped his backsteps to the exit and stood in silence, like when he was giving up on Seung Won's decision. The man stepped closer to our direction, we were cornered, we didn't have much option, dangerous men are waiting with their arms open, outside and inside. We closed our eyes, thinking that this man is going to kill us soon. 

But we were wrong, this man only put his right hand on Siwon's right shoulder and his left on mine, he gave off the same smile as the one he gave when he welcomed us here. "It's okay, son. I won't do anything to you, I promise." he assured.

The both of us sighed in relief, even though we're not really trust this man, at least he promised us. 

Siwon stared at him, but with a normal look he used to do. "Sir, why do you plan to keep us alive? Are we not a threat to you? And how do you figure out about ourselves?" he questioned formally and politely.

"Ah, you're not. Harmless children like you wouldn't be a threat to anyone else. I just pity you, you were really unlucky to have involved with your father's organization matters, and for that, I'm really sorry." he bowed in his apology, despite the age differences between us, he still put up some respect to us. "As for how I know about you, because Seung Won's lies was silly enough to be believed in, he always does that, and he always thought I was being fooled by his stupid, unlogical lies, you were brought here the same way." he explained.

Siwon chuckled, maybe because the situation was really tense and felt really real. He wasn't able to to think clearly when he saw his parents' death with his own eyes. He really regretted that he was deceived flatly.

"Your hair looked just like him, and your sister's eyes really resembled his. Anyone can tell if they saw you two together, don't worry, I won't tell anyone about this matter, not even Seung Won. Losing Ki Ho was really a big loss indeed, but we have you now, I now you have talents, I could see through your eyes." he praised Siwon deliberately. Siwon just smiled in embarrasment, this man really flattered him so much.

"Gomawoyo, sir." he thanked shortly.

"My pleasure, I'm so sorry for the loss of your father, Seung Won planned this himself because he was working excellently in the organization and that wicked Seung Won was jealous of him because he got all the praises from me, just like I did to you right now. I tried to stop him, but he wouldn't listen. Jealousy has driven him mad. I'm really sorry, please forgive me." The man apologized once more with a ninety degree bow, the both of us just bowed in return, this man really didn't have any bad intention on us, judging how many times he apologized to us.

"It's okay, sire, we forgive you. It's not like you did anything wrong, I was really delighted to hear that you tried to save our father, and that's enough for us." Siwon smiled childishly, finally he could send off his smile like a real child of his age.

"Please stop calling me sire, I'm not really worth that calling. Let me introduce myself, my name is Lee Soo Man, but I prefer to be called Seonsaengnim. Pleasure to meet you, Choi Siwon, son." he shook Siwon's hand manly, i was really happy to see some better view in front of my eyes, at least he managed to make Siwon smile, and that's good enough for now.

"Siwon, you truly hate that man outside, and do you wish to have revenge?" he asked. I was a little bit surprised upon his question, wondering what he's up to.

"Of course, I wouldn't forgive him for what he did to me and my family. I will destroy him, when I'm capable enough." Siwon stated.

"I see. Then, Siwon, if you're planning for a revenge. I would like to request you one thing : For now, please listen to Seung Won's orders and do as he told. Make him trust you, make him believe to things he wished to believe, make him proud, and once you're ready, I'll be willing to help you when that time comes. For now, I will watch you from afar, please bear with him, I know your journey will be long and painful with him, but believe me, the end will really worth it." Siwon smirked wickedly, who knew that Seung Won's master would even turn his back on him and decided to support Siwon.

"Always remember, I'm always on your side. Just tell me when you need anything." Seongsaengnim concluded his explaination upon his method of revenge, although I didn't like the main idea of their conversation, there was nothing I could do to stop them, Siwon himself just nodded, he agreed with the conditions of Seongsaengnim's plan, and his face told me he was really happy to hear it.

Suddenly, a faint knock was heard from the outside and Seung Won started to call us. "Seonsaengnim, are you done?" 

"Yes we have just finished our conversation. I'm sending the children out now." Seonsaengnim winked at us, telling us to go out as he wished for, the two of us nodded in response at him, and walked towards the exit. When we opened the door, Seung Won was already standing in front of the door, waiting for us. Siwon looked at Seongsaengnim once again, afraid that this might be the last time they'll see each other. Sengsaengnim just smiled at Siwon.

"Remember to keep our promise, Siwon." he bid his farewell sentence, and we closed the door of his room.

Seung Won looked at our smiling faces, the different ones he witnessed on our way to Seonsaengnim's room. Wouldn't be strange if he wondered why we suddenly turned happy. He clicked the elevator's panel, and we're going down. When we're on our way to the third floor, he asked us.

"What did Seonsaengnim told you? Did he told you something good?" Seung Won wondered.

"Yeah, something very great indeed." Siwon replied with the faintest smirk he ever showed.

"This is it." upon our arrival on the third floor, we saw strange machines of sport, half of them were new for us to see. We were awed by the technologies and the complex structures of these tools, but we didn't realize, these things have taken our childhood, our youth and our respective lives. These tools have been used by Siwon during his time as a trainee criminal, to train him to become the likes of Seung Won. We only realize this thing, on the next day. At that night, Seung Won took us to a tour on that 'Training Room' and finally brought us to the room we will use on Siwon's trainee days, our room was the only place where we can communicate with each other, where we can sigh a relieve.

And our definition 'Training Room' changed into 'Torture Chamber' or 'Lively Hell', on the day Siwon used this items.

Which happened, on the very next day.

After the day where we slept peacefully, someone banged on our door like he's on a rush. That noise woke us up, the person who was pounding our door shouted outloud to us. "WAKE UP LITTLE IMBECILES!!" 

I jumped scarily to Siwon's bed as he pulled myself within his embrace, that was the first time we experienced such a barbaric wake-up call. The person kept banging on our door on purpose to wake us up, Siwon angrily let go of me and started to run towards our room's door. He shouted from the inside. "WE'RE AWAKE!" 

"THEN DRESS UP AND GO GET YOUR BREAKFAST!! GO TO LEADER SEUNG WON AFTERWARDS!! YOU HEAR THAT DRAT?!" his shoutings ended with the last, loudest bang on the door. I was still trembling in fear while Siwon looked at  me worrily, their treatment here was really different from what we experienced in our house, Siwon could still handle it because he was older and he's a guy, but for me, who was still very young and fragile, really couldn't stand such treatment.

"Gwenchana." Siwon patted my back to comfort me, I released little tears in the morning, which is something I haven't done before.

"Oppa, will we make it...from here?" I asked him as I leaned on his shoulder.

He caressed my hair lovingly and wiped the tears off my face. "Everything will be alright, we'll make it for sure." he smiled at me, that was the last time I saw him smiled widely and sincerely. Because there's no peace in our days after.

We changed our clothes that's provided for the two of us since we left our belongings in our house and grabbed some breakfast. As soon as we finished our morning meal, another bulky guy showed up and pulled us somewhere. We didn't like the idea that we're treated like some livestocks, but we were still children, there wasn't anything we could do. He brought us to the training room, the place where we had our little tour the previous day, and Seung Won was waiting for us with a malicious smirk.

"So, are you ready for your training?" he asked, but Siwon only respond with his deathly glare. "I like that look in your eyes, that's the eyes of a true assasin. Well, let's just get things started." Seung Won flicked his finger to the bulky guy who brought us here, he unhanded Siwon and pulled me roughly. 

"Oppa!" I cried as the guy kept pulling me further away from Siwon.

When Siwon was about to catch up with me, Seung Won caught his hand and stopped him. "Let me go, bastard! What are you going to do with my sister?!" he struggled from Seung Won's grasp, but he was too strong for the little Siwon to handle. Siwon kept trying to escape from Seung Won's hand, Seung Won was really annoyed by Siwon's attempt and violently dragged his hair.

"Listen to me, idiot. If you don't wish to see your sister's corpse by the end of your training like the way you see your mother and father's death, I suggest you listen to my commands, and do as I say. Are we clear? Don't even try to play around with me, one wrong move and your sister's a goner" he threatened, Siwon chuckled, he remembered what Seonsaengnim last night about Seung Won and his bluffs, he thought he was practicing on Siwon right now.

"You can't frighten me." he replied confidently, with a fake smirk to him.

"Oh, I'll be more than just frightening, you thought I was bluffing, huh? Well, see this." Seung Won pulled out a gun from his jacket and held up the gun at me.

"No, DON'T!" Siwon screamed in fear while I closed my eyes.

The shot was directed to me. I thought I was about to lose my life at that moment, but the bullet was embedded on the ground, only an inch away from my feet. "Next time, I'll make sure I won't miss, if you wouldn't listen."

Siwon gulped his saliva, he realized challenging Seung Won would only means losing me. He has no choice but to kept silent, as the bulky guy continued pulling me somewhere, the both of us looked at each for the last time worrily, asking what's coming over us.

Our first morning on our new home, turned out to be a total cruel disaster.

I surrendered to the guy since even if I could get away from him, I couldn't do a thing right without Siwon. All I did was crying hardly, after a while, we stopped our tracks and I found out I was standing in front of a room, the room's door was the sliding type, metallic and it was really thick. The guy opened the slide door and threw me inside the room. "From now on, you'll be staying here until your brother's training is finished."

"What?! I don't want to! I want to meet Siwon Oppa!" I cried loudly at him, but he refused to listen. "Shut up, girl! You'll be meeting him at night, and don't try to do something funny, we have you on our security camera." I barely understand what he meant by security camera, but what I caught was that I have no chance of running away.

"Besides, look at the window." I did as commanded and turned my head to the glass window. There, I saw Siwon was being tortured, whipped, punched and even kicked by Seung Won. I ran closer to the window and shout at him. "Siwon Oppa! Siwon Oppa!" he didn't respond to my call, he just keep enduring the pain he's been taking from Seung Won's torture, the wasn't an element of training, only sheer persecution.

"You'll be seeing your brother for most of the time, don't worry. You won't be missing him even for a second." he stated heartlessly.

"Oppa! Oppa! Oppa!!" I continued to call his name, I thought my voice wasn't loud enough.

"Save your energy, noisy brat. He couldn't hear you nor see you. See you at lunch time, enjoy your time here." he slided the door hardly and he locked the door. "Don't leave me here alone!" I ran from the glass window and pounded on the entrance continously, it ended up no avail, no one heard me, and I was stuck on the glass room, with a view of Siwon being tortured by Seung Won. 

That's how I spent my whole childhood, how we, children of Choi family spent our youth. When kids our age were having fun with their toys, parents and friends, we lost our parents tragicly,the only toys for Siwon were those exercise machines that he used everyday, and we were locked in the dark world, having just one friend would be like a dream come true for us

I stayed clueless on that glass room while watching at Siwon worrily, my tears wouldn't stop from falling, he was really having the very definition of 'hard time', Seung Won treated him like an animal, he made mistake, he got some whip, and that happened over and over again, all I could do was watch, while taking some bitter lunch and dinner from the guy who kidnapped me here. I didn't know whether it was noon or night since there was no window nor clock, the only thing that gave me the trace of time was my meal time.

The only thing I did was praying for our safety, to help us getting through our day. I even protested to the God, he has taken our parents lives, and even put us in such cruel situation that wasn't worth called 'living', frequently I asked why he did this, but he answered, long after our punishments was carried in a long term. 

There is one thing we waited in our days, though : Night time.

Few hours after my dinner, the bulky guy returned to the glass room and picked me up, I thought he was going to hurt me like Seung Won did to Siwon, but he only said one thing. "Go back to your room, punishment time is over."

I walked slowly to the door and kept turning my head back, afraid that he might hit me from the back, he did nothing to me and let me peacefully head to my room. Siwon wasn't there yet, I waited while looking on the clock on the wall. Few minutes later, he came back in a tattered condition. He collapsed on me while I was sitting on the bed.

 "Are you okay? What did they to you?" he asked worrily with a weak smile, while hardly panting.

There were so many things I wished to share with him about my dreadful experience, then again, I realized that pain that I felt wasn't comparable to his, and I knew, telling him my story will only increase his pain and worries, I grinned at him childishly and acted like nothing happened to me.

"I'm okay, Oppa. Don't worry about me." he smiled at me in return and slept on my lap, at that moment, I realized that was one of my wisest decision of my childhood. I smiled at him while dripping tears on his cheek, it was a long, tough and painful day, but the smile on his face while he's sleeping made up all the terrible things that occured to me to today. I know telling him everything wouldn't change a thing, even though I'm dying to tell him all about it, I asked myself not to be selfish.

And I decided to keep it that way, forever.

"Saranghaeyo, Siwon Oppa." I laid a chaste kiss on his forehead.

Author's Note :

Annyeonghaseo, my fellow readers. Okay, first of all, please forgive me for the very, very late update because I barely had time at the last weekend because on 10th of February, Umma had her birthday party, and on the 11th, Appa had his turn, sweet isn't it? ;) anyway, I hope this chapter is long enough to fill your daily activities with a smile, here's another Siwon's past, that you might want to know.

I'm so sorry for stalling his past on and on, the chapter was way longer than I expected and "Siwon's past section" should be coming to an end on the next chapter, I hope so, if my mind doesn't get me a new idea. I think the YoonWon moments would last until Chapter 31, because there's still an incident that will happen on the hospital, YoonWon shippers should really anticipate it because I always thought the chapter I think of really will put a change on the story. And for YulHae shippers out there, I'm really sorry if you're waiting for them and please don't unsubscribe me, I'm making the future plan for those two, too :)

Lastly, I want to say happy birthday to Choi Sooyoung who just had her birthday on the 10th February last weekend (which is the same as my Umma) :) I'm so happy for you noona, I hope you stay healthy and beautiful. For me, this chapter represents my birthday gift to you, I'm sorry I couldn't make it in time if you read this (lol) because I was busy with my own family, don't worry you're still my favorite Choi sister and my beautiful shikshin :D the readers must be happy for you two.
