Nakamoto Yuta is a Japanese exchange student who was transferred to your class a few months ago. He's quiet and silent, doesn't talk to people and has a closed indifferent expression, even scary at times.

This week you have been receiving love notes that are left in your locker. You don't know who they are from, but you can't deny that the notes are cute and very well written. Your curiosity to know who the sender of these letters is increases more and more.

As class leader today you stayed late at school to finish solving some projects in your class, the sky was already dark and no one but you was there. Before leaving you go to your locker to store some materials, when you open it you see another note. A smile comes to your face when you take the paper.

For a moment you notice that the red ink used to write the note was running, so you run your finger through the paper, at that moment you notice something scary. That wasn't red ink, that was blood!!!

Before the smile on your face fades completely and you scream, you feel a hand on your mouth and another hand on your waist. The person who catches you immediately pulls you into an empty room close to where you were.
