You and Bangchan are arguing right now before he slaps you, your cheek stings,he had so much anger from that moment, he was about to punch you but he refrained from doing so and he punched the wall, he thought you were cheating on him with Hyunjin

Bangchan: just get the fck out you sl*t.

You did exactly that, he felt guilty as fck as he found out Hyunjin hadn't been in the city for a bit so he couldn't have cheated with you, your school was having a farewell party for the high school seniors and obviously he was there, he wanted to hold you and apologize a million of times. to make it worse, you were dancing with your friend on stage to a desi song(London thumakda) in a green lehenga you even have a bandage on your cheek from the slap, but what surprised him the most was that you cut your hair and he got more obsessed. Suddenly, your ex, Soobin comes over and sees the bandage on your cheek

Soobin: who the fck slapped you? Tell me right now I will fck them up.
