Kitty Cat Love [Neko! Aoi Satsuki Love story] Tsukiuta love story

Males are born as nekos, they are branded on their arm at the age of sixteen for who they are bonded to be by a certain color. If the male rejects, breaks up or hurts his S/O in any way he'll turn into a cat until his S/o loves him as himself once more. Will Aoi be able to love his S/o or will it be a challenge for him to be as a cat like male?
