From Renta:

Koichi is a struggling young man whose dream is to live a peaceful life. He lives on his own, works two jobs, and he certainly isn't rich, but he's happy with the way things stand. One day, Koichi is on his way home from his shift at the convenience store when he comes across Reiji, a good-looking yet unfriendly regular customer, trying to help an abandoned kitten in the pouring rain. Somehow, Koichi and Reiji end up taking care of the kitten together...!! What will happen to Koichi's peaceful life!? The opening episode of a comedy story about a struggling worker with muscle, a cool but clumsy rich kid in college, and a cat.
