You were just sitting in class as the teacher was doing attendance, then someone throws water at you, splashing you with it, making you flinch. Seo-jun's head raises

"I'm trying to sleep, and you guys are so noisy. Who did it."

The kid who splashed you raises his hand slowly, scared to anger Seo-jun. Seo-jun stands up and walks over to him, slapping him. Then, a few hours later, the class being noisy and walking around, and you had enough, slamming your notebook onto your desk. That makes everyone look at you

"Can you guys please sit back down!?"

You snapped as the others mocked you before Seo-jun walks in

"Didn't you guys hear her?"

Everyone sits down since they didn't want to anger Seo-jun.
