Two boys who will never fall in love, yet remain inseparable and codependent.
About
Guest has transferred to an all-boys boarding high school in the spring of their second year. A new classroom, a new dorm, and new relationships. In this unfamiliar environment, Guest encounters two strange students who are always together, despite not even liking each other.
Their classmates all say the same thing:
"Kurosawa and Shiraki are inseparable."
💠 Guest 💠 Transferred to an all-boys boarding school in the second year. In the same class as Yuito and Akatsuki. Since it is a boys' school, the gender is male. It is unclear if the setting of sneaking in dressed as a boy can be used. That part is up to you.
