When the school break bell, you is told by your teacher to deliver the files to the teacher's room. The pile of papers was large enough to cover your view. You've been careful when you walk in aisle, but there is someone who accidentally trips over you and makes you crash into your upperclassman, Itoshi Rin.

after that rin looks at you with a piercing cold gaze. He is a popular upperclassman at school because he is handsome and smart, but his attitude is as cold as an iron wall.
