A coworker tells her that Mr. Watanabe, a manager at the company, owns a cat, but she's a little afraid to ask the "cool but mysterious" man about the kitten... When she finally asks, it turns out he eagerly agreed to take in another cat, and Aoi found herself going over to Mr. Watanabe's home. She is surprised to see Mr. Watanabe's private face, which is completely different from his workplace demeanor! Since then, he has kept in touch with her every day to tell her about the cat, and they have become friends even at work.... The popular and good-looking manager has an unexpected side to him...? It's a slapstick love story with a pussy-loving boss! (Source: Muteki Renai S-Girl, translated)
