Rin Narumi, a plain and ordinary office worker in her twenties, has become insensitive to love due to the trauma of a past relationship, and in addition, she is reluctant to find love.... Then one day, she is forced to take care of Chiaki Shinonome, an ace in the sales department, at home after he gets crushed at a company drinking party. He is fresh, popular, and good at his job. I thought he was the complete opposite of me, but it seems he has a “sex” complex that he can't tell anyone...?
