'' We really need to talk '' 

'' Are you going to convince me that I have to get married again? '' I sarcastically said folding my arms 

'' Listen, Ji-na, I am really sorry- '' he started

'' Sorry? do you think by saying sorry will erase wha I felt and what I am feeling?  '' I asked my voice getting higher 

'' I know it won't change anything but I am still going to say I am sorry '' he yelled back and kept walking till he got closer to me. He took my hand and we both sat at the end of the bed '' Listen, you're my only family and the only person on this earth I am ready to do anything for. You're my other half, Ji-na. So you can't really blame me if I was worried about you '' he added his hand still holding mine

'' But that doesn't mean you can talk about marrying me like that, it really hurts and all I felt was that I am only a burden to you '' I whined

'' You know very well you're not a burden. I just wanted you to have your own life and be happy but I guess I didn't show it in the right way '' he explained and smiled slightly '' In my job, it's not guaranteed that I will come back alive when I leave on a mission. And every time I leave, I can't keep but wonder what will happen to you if something happened to me. I just can't help it, Ji-na. I know I was insensitive back in Busan and I didn't think much of your feeling but believe me, I didn't do it to hurt you or make you feel small or whatever, you know I can't do that '' 

'' I know, Oppa. But it's just the way you said it, it's just... '' 

'' I am sorry, okay. I know you're big enough and independent but I still see you as my little sister who used to hide behind me every time she saw a clown because she was so scared '' he said and chuckled

'' Yah! They are really scary! '' I defended and I smiled as well 

He then held my hand with both of his and looked at me '' I won't force you to marry anyone, nor I will send you away. I can't bare to live without my twin sister, you know '' he added 

'' Me neither '' 

He smiled wider '' Are we cool now? '' he asked

'' Hmm, only if you promised to make me dinner tomorrow  '' I answered enthusiastically 

He ruffled my hair '' You only think of your stomach '' he clicked his tongue '' But I will do it '' 

This time, I snuggled closer to him and hugged him '' Thank you for being in my life, Oppa. I won't be able to survive without you '' I said and felt him hugging me back and kissing the top of my head 

'' Sleep now, okay? you must be tired besides you have to work tomorrow '' he said after a few minutes

'' I really don't want to go to work. I just want to stay with you '' I whined then pouted

'' And what about Leeteuk? Don't you want to see him? '' he suddenly asked and I removed myself from him 

'' What does Leeteuk has to do with this? '' 

'' I wasn't the one who said I am willing to marry him a few hours ago '' he teased and I rolled my eyes 

'' I was just angry, I never meant that '' I argued 

'' Really? '' he asked amused while wiggling his brows 

'' Just get out! Aish! '' I groaned and hit him with my pillow. He kept laughing and then he finally left. 

I am willing to marry someone else if he just wasn't too dense to see the truth... 

The next morning, I woke up to find Seung Hyun already awake and prepared breakfast. We ate and talked like nothing ever happened until he mentioned Jiyong. 

'' You were really mean to him, he was just trying to help '' he said

'' Whatever, he was mean too. He shouldn't have yelled at me '' I defended. I was actually still hurt but it wasn't because he yelled at me. I was angry and hurt because I didn't mean anything to him that even when they were talking about marrying me off, he didn't sound bothered. 

'' Are you going to meet Ji Hyun today? '' I asked before he could answer. He understood that I was trying to change the subject and I was glad when he let go 

''  Mmm, I am meeting her in two hours '' he answered

'' Oppa, I am really happy that you're finally taking a step ahead. I hope you'll be happy from now on. Ji Hyun is a really good girl and I wouldn't accept another girl except her with you '' I told him honestly 

'' Thank you '' he said and smiled '' I can't wait for the time when you too will find someone '' he added

'' I thought we already agreed last night that we won't talk about marrying me off again '' I whined

'' Easy there. I didn't mean anything, I was just expressing that it would be nice to have someone, no more, no less. I won't force you into anything '' he quickly explained 

'' Okay. I have to go now or else I will be late. Say hi to Ji Hyun for me '' I said as I quickly stood and went to take my bag and coat '' Don't forget your promise, I am expecting you to impress me '' I yelled from the door

'' Don't worry '' he shouted back and with that, I walked off.  

Once I reached the lab, no one was there so I took my time drinking the coffee I brought with me. Just when I sat down and took the first two sips, the two sprung open and Dr.Lee came in. 

'' Good morning, Dr.Lee '' I quickly greeted and bowed 

'' Good morning, how was your holiday? '' he asked

'' Relaxing '' I simply answer

'' Good, because I think it's time for you to start working on your new task '' he added and I nodded he then handed me some files and USB flash drive that I didn't realize he was holding 

'' Those are what you'll be working on from now on. Forget everything else. I already gave your work to Leeteuk so you'll be free and focus only on this and remember that you'll be paid for this once you finish '' he added and I again nodded my head

'' What am I supposed to do '' 

''  You have to find the effect this nuclear weapon has on people and how to stop it. You'll find some of the effects here in these files but they all theories so if you find
