Sorata Kanda fell in love with her instantly when he laid his eyes on her for the first time. The catch was, "she" was a feline named Hikari, and the school regulations prohibited dorm residents from owning pets. Consequently, Sorata was sent to the notorious Sakura Hall, a haven for problematic and unconventional students like Ryuunosuke, a promiscuous womanizer, Jin, Mashiro, a talented artist with poor life skills, and a reticent recluse. Dorm supervisor Ms. Sengoku assigned Sorata the responsibility of caring for Mashiro, along with his expanding cohorts of stray cats.
