Mostly Yoonbum x reader x Sangwoo

In my story
YOONBUM DID NOT STALK SANGWOO
After they met eyes, SANGWOO dropped his wallet one day and YOONBUM and since YOONBUM is kinda awkward He decided to go to his house and give it to him. When he did SANGWOO invited him inside. Yoonbum foolishly excepted.

This is where your character, Areum Hye comes in.

You are a complete badass and kinda crazy, and have been friends with YOONBUM since the last year of middle school. You guys used to talk everyday but one day he just didn't pick up the phone. But then you see him with a guy, looking like he's been through hell and back. Something's of about the man behind him and we're gonna figure it out no matter what.
