ON PHONE

"Sir, the result is out." -Doctor-

"How was the result?" -Jonghyun-

"Their hair DNA matched each other well. They're father and daughter." -Doctor-

*paused*

"I see. Prepare the document for me with writing their name on it. I'll go to pick it up when I'm back from my business trip." -Jonghyun-

"Yes Sir!" -Doctor-

Jonghyun has secretly stole a few strands of Mr. Kim and Yuna's hair to do DNA test after he heard Jin talked about something weird on rooftop. He stole their hair when they were admitted to hospital together a few weeks ago.  

Now the result is out but Jonghyun has no time for it. He has to leave for his business trip in the evening and he wants to spend most of the time with Yuna so he keeps it with doctor in charge until he's back. 

Jonghyun was really surprised with the result. He assumed Jin also found out about this but Jin tries to hide for some reasons. 

Jonghyun decided to keep this secret with him for a while and will solve it after he comes back from his abroad mission, just to make sure Yuna won't need to face this fact alone.

< At Jonghyun's Office >

"It's so fast... So you're flying tonight." Yuna sobbed inside her lover's arm while sitting on his lap.

Jonghyun hugged her waist tight while burying his head on her chest, feeling so lonely already. 

"I miss you already, Jonghyun-shi." Yuna couldn't hold her feeling as in the evening, Jonghyun has to go. 

Jonghyun felt so much heartache that he found it hard to speak up... 

"One month is too long for us. I don't wanna go but it's for work. Please take care of yourself well! Let's always contact each other. I love you. Please wait for me!" Jonghyun tearfully said with his low, shaky voice. 

Yuna nodded. "Good luck! Please have safe flight!" she gave him an unhealthy smile through her tears. 

Jonghyun wiped her tears then cupped her face. 

"I'm so sorry for not being able to let you send me off. My family will do it and my mom will be there too so... I don't want you to face them. So this is gonna be our moment before I leave, my love. Let me hug you from now to the last minute." he apologized for something he isn't capable to do. 

Yuna cupped his face back with a brighter smile. "I'm sorry for being weak in front of you. My tears make you worried. I'm sorry. I should smile for the rest of time we're having at this moment. I'm such a bad girlfriend." Yuna apologized back for crying in front of him. 

She quickly wiped her own tears. "Alright, I'm not crying anymore. I'll show only my smile to you so that you can go with smile too." she forced her smile to him. 

Jonghyun softly patted her head and hugged her tight again. 

After a moment, Jin came in. 

"Oh I'm sorry." Jin startled to see the couple was having their sweet time. 

The couple broke the hug. 

"Hmm you called me, didn't you?" Jin asked. 

Jonghyun nodded then turned to Yuna. 

"I have something to talk with Jin a little bit. Please wait me outside! We'll have an early dinner then I'll drive you home before I'm off to airport." Jonghyun said then Yuna left both good friends alone. 

Jin walked to Jonghyun. 

"What do you want to talk with me?" Jin started the conversation. 

Jonghyun didn't reply right away. He opened the drawer of his desk then took out something.

"Do you remember this necklace?" Jonghyun showed the necklace Yuna threw away long time ago to show Jin. 

Jin wasn't shocked to see this necklace as he used to see it before and he knew the history of this necklace but he was shocked when Jonghyun asked like that. He couldn't speak out anything. 

"Why do you have to be this shocked? It's not your first time to see it... You saw me pick it up from dustbin when Yuna threw it away long time ago..." Jonghyun tried teasing Jin. 

Jonghyun put the necklace on the desk in front of them then crossed his arms, acting like he is about to catch a criminal. 

Jin turned away. He became so awkward. 

Jonghyun scoffed. "Alright..." Jonghyun hit his desk a little bit then got up from his armchair. He walked to stand near Jin.

"I'll let this be for a while as I'm leaving South Korea soon but when I'm back, let's talk about the thing you're hiding between uncle Kim and Yuna." Jonghyun spoke out something that shocked the hell out of Jin. 

Jin turned to look at Jonghyun with his eyes wide opened.

Jonghyun looked so serious which made Jin even more uncomfortable but he couldn't ask or say anything. He was too nervous. 

"But I know you will protect Yuna because if you don't, you're not human anymore. I hope you won't let something bad happen to your half....." Jonghyun paused. 

Jin jaw dropped even the sentence wasn't finished yet. 

"I was so worried about Yuna's safety but now I believe you'll take care of Yuna well and in the name of whatever you want..... Jin, please make sure she's safe. It's your duty." Jonghyun finished his words, grabbed his stuffs then left the office.

"God!" Jin burst into tears after Jonghyun left. 

"Has he been following me? Has he found out? This is getting more stressful. What should I do?" Jin stressed out alone in Jonghyun's office. 

After a while... 

"Whatever like he said I have to make sure Yuna is safe. She doesn't deserve anymore pain both physical and mental." Jin committed to protect Yuna at all cost.

-----

Jonghyun drove Yuna home after the farewell dinner. He wouldn't let go of holding her hand even he is driving. 

"Yuna, make sure to tell me everything happens to you and let's always keep in touch." Jonghyun kept repeating the same phrase all over again.

"I know. You too, please tell me what is going on with you everyday too. I'd love to hear everything." she sweetly replied. 

"Jin too." Jonghyun suddenly mentioned about Jin. 

Yuna frowned. "Huh? Jin-shi, what?" Yuna curiously asked. 

Jonghyun controlled his feeling before replied. He felt so emotional all of a sudden. 

"If there is any trouble, please call Jin. Ask him for help because I'm not with you. Got it?" Jonghyun replied. 

Yuna waved her head. "No, I won't ask help from him. Why would he help me? I'm the reason that makes his sister hurt. I stole a man his sister love... He has no reason to help me." Yuna refused with her upset. 

Jonghyun softly rubbed her hand. 

"Although my friendship with Jin is a little ruined, I know this man clearly. He will do what is right. He is glad to help you. I mean to think everything all over again, he is so protective over you. He always warns me not to hurt you, warns me not to play with your heart, punched me when I forced you to sleep with me, threatens me to take care of you well..... Don't you think he is a protective brother?" Jonghyun recalled all past moments when Jin is being so protective over Yuna and him and even mentioned Jin as a brother. 

"But he's not my brother. Why would you call him a protective brother of me?" Yuna continued asking with Jonghyun's weird words. 

"We actually have a lot of things to talk but let's wait until I'm back. If I say this now, it'll be getting so complicating as I'm not present here for a while. I won't let you face it alone. Wait me until I'm back." Jonghyun hinted her he has somethin
