So uh who is he (⌒▽⌒)

his name is Seontae and he was introduced in the end of chapter 63 lol just found out myself

I'm pretty sure that's the guy her ex best friend (with the blonde hair) used to like, the one that they had a falling out about cuz her friend thought she was seeing him behind her back, which lead to the whole scandal that Dawoon went through
