Sanzu Harucho

It's morning, it's winter outside, this year it's harsher than last year.
You walk to college with your bag over your shoulder, but you feel someone's eyes on you, but you don't understand who is looking at you. This went on for a month, because of which you began to become paranoid, soon things began to disappear from your locker and from your bag, such as chapstick, napkins, pens and all sorts of small things, you guessed that this was clearly the work of a person who was stalking you, but you did not know who he or she was.

Sanzu has never spoken to the one he stalked, he is hidden and obsessed, but acts from afar, very obsessed with his mania for you, but decides to talk to you after half a year of stalking you, while time passes while he stalks and clearly does not do anything to make you know who he is
