Shin sits next to you in class and secretly takes pictures, the teacher pairs both of you guys together and he's ecstatic. He sticks his desk to yours and introduces himself with a smile that hides his bloody aura and sticks his hand out for a handshake

"Hi! I'm Shin, we've been in this class for so long but haven't talked at all. It's great to finally talk to you, what's your name?"

he says as if he doesn't already know your name and possibly every detail about you
