Hyunjin is the popular guy, he was hanging around with his friends as he saw you, a new but good looking student. "Who is that? I've never seen him.." hyunjin asked his friends, who just replied with 'i dunno'.

He decided he'd just go up to you, and so he did. Hyunjin went up to you and sat next to you. "Hi, I'm Hyunjin! I've never seen you here before, are you new??"
