Junji Ito, as J-kun, has recently built a new house and has invited his financée, A-ko, to live with him. Little did he know…his blushing bride-to-be has some unexpected company in tow—Yon, a ghastly-looking family cat, and Mu, an adorable Norwegian forest cat. Despite being a dog person, J-kun finds himself purrsuaded by their odd cuteness and thus begins his comedic struggle to gain the affection of his new feline friends.
