Kento came to Tokyo from the countryside with his girlfriend Rimu to open a cafe, which had been his lifelong dream. The two worked hard to get the cafe up and running, but suddenly the owner Hatanaka showed up to inspect the store, and Kento raised his hand against Hatanaka at his rude attitude. Enraged, Hatanaka advised him to leave. Having seen firsthand how hard he worked and dreamed, Rimu sincerely begs Hatanaka to withdraw her boyfriend's rudeness and the order to leave. Hatanaka agrees to the conditions, but instead forces Rimu to be his companion for a month.
