Aaaand he played it as loud as possible-at the point Katsuki could hear it-and he was 5 rooms away.
LMAOOOOOOOOOOOOOOOOO-
"What the hell-"
Sero then turned down his music, aaaand guess who came out his room to complain?
Katsuki stomped out his room, phone in hand, slamming his door shut.
K: "CAN YOU MAKE YOU'RE MUSIC SHUT THE FUCK UP?!?!"
Oh shit was he pissed-AND OH WOULD YOU LOOK AT THAT-He was on a class with Kaz-AND OH-HE FORGOT TO MUTE HIMSELF. HOW LOVELY.
Ok but Sero how do you even know that!? Oh right-you heard her singing...um...her dorm's literally a solid ten doors down from yours sweetie-HOW THE HELL DID YOU HEAR THAT!?
Before he could even get there the music was turned off-she was honest-to-god just doing it in an attempt to get Sero to shut his goddamned music off.
