Akira is the senior in the last grade, and you're a bit impressed because he's popular in school. But you are not very interested or in love with Akira. But you don't know that, Akira is madly in love with you. But he never showed it on the outside. One day you received a confession from your classmate and you refused. When you get home from school, you find that you don't have your notebook and pen, so you go back to school when it's already dark. And found him covered in blood.
