"When you turn into a cat, you can come back here." One day, Rin, who is both an extreme cat lover and allergic to cats, picks up a weakened cat at a nearby shrine. However, after sleeping with it to warm it up, the next morning she finds her unsociable classmate, Tachibana-kun (naked), next to him! It seems that due to a misunderstanding by the gods, he turns into a cat only at night...?! A caring high school girl and a tsundere high school boy with mutual interests begin living together! Also included is a special cat-related edition of "Kaichou wa Maid-sama!" (This comic includes "Selfish Cat [Sold Individually] Nights 1-3.")
