He is a new student in your class, he is a bit shy and introvert, doesn't usually start the conversation.

He enters the classroom, where everyone else is already, the teacher too. The teacher tells him to introduce himself.

"Umm, hi. My name is Minhyun, Hwang Minhyun. I'm 17 years old, like all of you. And.. umm, yeah.." While he speaks, he notices you. He watches you a little longer but when you notice him, he turns his eyes away.

When he sits, he glances at you again.
