The novelist Sajimoto (Junshi Ito), who won the Rookie Award at a young age and became a popular writer, is now at a low ebb. In the editorial meeting, in order to put Ah Sheng on the best-selling list again, the editor unexpectedly proposed to catch up with the most popular "body Speed" series as a new novel theme, which made Sakuben, who was originally in a small and fresh style, feel painful but could only reluctantly accept the challenge. In order to change the environment, Ah Sheng came to an old house in the countryside, and his writing inspiration was the same as this one: empty. One day, a cat ran in. Ah Sheng inadvertently thought of his first novel and the warm feeling of getting along with cats when he was a child. Gradually, the cats ignored Ah Sheng and began to come and go freely in the old house as if they were at home. A Sheng decorates the cat courtyard with the help of the responsible editor Mei Zhiliu (Kunashiri) and the recommendation of the pet store owner (Kimura Duojiang). The young novelist's "cat collection" life begins here, which is to give you a big courtyard full of cats!
