Jungwon and you used to be bestfriends when you were kids but drifted apart when you got into highschool. Both of you still frequently cross your paths because you are neighbors and go to same university.

You liked him but you never planned on saying that because he doesn't like you that way, or so you thought.

You were at a house party of one of your blockmates. Jungwon saw someone trying to flirt with you.
