You have been friends with each other for like 14 years since junior high school starts and you and him were nothing but friends but somehow someday you heart beat faster than usual and you realized a crazy phase. U may like him more than  friend should do?

Ong seongwoo - engineer. basically tops everything. Visual talent academics since childhood but super clingy and cheesy and such a very good friend that all girls wish they were you.

You. Park jaekyung - own  a small bookcafe. Just moderate in everything. Seongwoo's bff 

Park Jihoon- jaekyung's crush which happened to be in ong's squad

Wannaone - ong's squad

Park minah - jaekyung's cousin plus bff.
