Ai has a strange condition passed down in his family in which his sadness causes him to turn into a cat and that's made it hard for him to live a normal life and make friends at school. He's determined to change and live a normal high school life as he starts his first year, but he quickly runs into trouble and is saved by his new desk neighbor, Kurokawa. It feels like Kurokawa keeps seeing embarrassing sides of Ai, but Kurokawa is so kind, Ai badly wants to be his friend, and soon, possibly even more. A very cute comedy BL with some slight translation errors that honestly only add to the charm in my opinion. No trigger warnings.
