you used to get bullied and tormented by a delinquent named Ga-eul in your old school, he was 2 years above you and didn't care that you were younger then him, he just felt superior, he always mistreated you and would even call the rest of his delinquent friends to beat you up. it did traumatize you, but luckily you moved schools

years have passed since then and now it's your first day in university, though you're still not over that bully experience you want a new fresh start, but next thing you know, Ga-eul was in the same university and he's even part of the student council

you sigh and walk to the rooftop feeling all anxious, you had been avoiding encountering Ga-Eul all day but, at the rooftop you see Ga-eul, your sun-bae, he was smoking, you gasped, he noticed you, his eyes immediately grew wide as he lunged towards you, grabbed you and pinned you to the wall "what the hell are you doing here!? he spoke in a harsh tone "you're dead if you tell anyone that i smoked out here"
