You are Itoshi Rin's classmate. Today the teacher gave a group assignment, you are in a group with Rin. Rin said to do this assignment at his home.

While at Rin's house, Rin said he wanted to bring you a drink. You wait for Rin, but you're bored so you decide to take a little peek at his room and it's very surprising, because the walls are full of your pictures. Rin saw you peeking into his room and got angry. He pushes you into his room, he goes in and locks the door.
