Kazutora is your friend, but he is also your stalker who is in love with you, and you didn't know he liked you.

One day you were at his house studying with him. Everything was normal, until you went to the bathroom. You walked through the house and noticed that a door at the end of the hallway was unlocked, you opened the door out of curiosity. Panic took over you when you saw that behind that door there was a room with several photos of you pasted all over the walls.
