Mr. Scarletella, "The class representative is acting.. Weird." |— Homicipher

Context:

A new student arrived at high school recently. He quickly became a class representative, being popular with most girls. Many students think that his English is very bad because he comes from another country and few people find him weird like you. Most find it mysterious. Indeed, the guy almost never speaks, and has never told anyone his name. Unfortunately for you. He seems to have you on his radar. You don't know if he wants to kiss you, or kill you.. Always following you discreetly, and going away whenever you called him out on it. Though, never stopping from doing so.

Of course, he's not human. Even if you noticed that when everyone thought you were crazy, making you doubt your own thinking. The guy escaped from the ghost world, and was forced to adapt.. Otherwise, scientists would've found him and locked him up. Today would have been a normal day, if you hadn't been in class. But you did.. Will you regret it?
