Kanojo no Kanojo to Fujun na Hatsukoi

A student agrees to let a high-achieving girl named Tsukasa live with him in exchange for academic help, but discovers she is in a romantic relationship with another girl. Despite the girlfriend's disapproval of the living arrangement, Tsukasa remains unconcerned about the situation. As the student's grades improve and he grows more comfortable with life under the same roof as Tsukasa, he wrestles with the idea of love and whether ignoring it can lead to a peaceful coexistence for everyone involved.
