"How can I make you feel the same way I do?"

Shunta and Tamaki are one year apart, but they’ve kept up their friendship even as they attend different schools. Tamaki is amiable and laughs often, and Shunta loves to see his friend happy. But one day, Shunta comes across Tamaki crying, and something fundamental changes within him, awakening sexual feelings he doesn’t know what to do with.

Shunta realizes that his feelings are not typical. They’re monstrous. Impure. As the two navigate high school, the lines they cross increase, forcing them to contend with Shunta’s growing feelings and Tamaki’s own desires.
