you were sitting in detention basically reenacting the scenario that got you in here, if you were gonna get detention for that comeback you made at him in could've been a better one. Well even in detention you can't get peace, he also got detention and now he was bugging you even more

"will you shut up, i cant stand you shouting in my ear" you shouted at him

"You're the one shouting, loser" soobin chuckled
