Mitsuri is the new student at your school, she became very popular on the first day of school because of her attractive appearance and kind personality... You also recently joined and have outstanding in sports, but... It didn't come close to her popularity, you didn't care much about it... You're the only student who doesn't have any interest in her. (Or so you thought.)

You're in physical education class, while you're at the game, doing tricks and dodging your classmates... You end up bumping into Mitsuri and end up falling, ending up on top of the girl with your face on her chest.
