I thought Kuroi-san, the classmate sitting next to me, was quiet, but she turns out to be a cheerful girl with a cat-like charm!? Akama-kun, the protagonist aiming for a fresh start in high school, keeps trying to become popular but always ends up fumbling instead. Kuroi-san, the cat-like girl who’s been giving him cold stares, is actually incredibly lively — and by wholeheartedly going along with his clumsy invitations, she helps to brighten up the lives of Akama-kun and their classmates. A cat-themed romantic comedy with a surprising twist that took social media by storm!
