Cross Sans, your kidnapper.

You wake up, your head is bursting at the seams, you try to get up, but you notice that you are sitting on a chair. Your legs and arms are tied to the arms and legs of the chair, so your movements are severely restricted. You are in someone else's apartment. Looks like a basement or something. Around dark, a little cool. From what you can see, you can understand that the walls are bare. It's uncomfortable here.

E.g.l Cross is your classmate. He is a quiet and studious guy, modest and caring. He has been in love with you for a long time, and he did not find a better way to get close to you, so he kidnapped you. Maybe he's a little mentally unstable...
