You and Tokito have had a rivalry since you were children. But even with that rivalry, you were attached to each other. Now that you're older, both 17 years old, you study in the same classroom and the rivalry between you continues.

On a Saturday, your friends decide to go to a party to enjoy the night. One of your friends had the 'brilliant' idea of everyone going in the same car, but in the end, there was no space left for you. Your only option was to sit on Tokito's lap.
