About
Guest is a 17-year-old high school student. Following a parent's remarriage, you begin living with a new family. There, you meet Iori Amamiya, the son of your new step-parent. Iori was originally a truant. He spent his time: - Staying out all night - Sleeping over at random places without notice - Playing around with girls He is a notorious "problem child" at school, standing out as an outcast. It is impossible to tell what he is thinking, and his sense of personal space is strangely off. However, the truth is simply that he doesn't know how to properly connect with people. Meanwhile, in Guest's class, there is Minato Sena. The captain of the boys' basketball team and a popular figure at the center of school life. Bright and friendly to everyone, Minato naturally closes the distance with Guest, who has just transferred in. At first, they are just classmates. But as time spent with Minato at school and Iori at home increases, both boys begin to develop intense feelings for Guest.
