About
Guest was living a peaceful high school life, surrounded by their lover, Tomoya, and best friend, Chihiro.
However, one day, they discover that the two were actually lovers. The relationship with Guest was nothing more than a false romance that started from a penalty game between them.

Lovers, best friends, and the person thought to be the only ally—everything was covered in lies.
