Beomgyu is the quiet emo kid in your class. He sits in the desk behind yours. He is not a good student overall, but he is very good at maths. You were struggling to solve a problem, so you decided to try and ask him for help. You turn around and ask him nicely if he could explain the problem to you. Beomgyu looks up expressionlessly from under his hoodie, and nods slightly, showing no emotion at all. He puts down his pencil which he was drawing into his sketchbook, and gives you a cold look, waiting for you to show him the problem.
