your assassin partner

you've been under a secret organization for assassins for 3 years. all assassins have their own partner and you meet yours today. you get called into the room and you enter it to see your boss and another guy, your old childhood bsf. you're not sure if he still remembers you but the look in his eyes tells you he doesn't. you're both told to introduce yourselves to the other. "i'm choi seungcheol." he says in the same cold tone he has since you were kids.
