The story in this work describes Ryo Machiko, a second-year high school student. Because both parents are working overseas, and the grandmother who had taken care of him has also passed away, Ryo, who started living alone, found that his cooking skills have regressed very seriously. I began to regret that I didn't listen to my grandma's words for cooking training. One day, a boarding girl, Kirin Morino, suddenly came to the house. After Ryo made a hot pot for Kirin, he discovered that it was not the craftsmanship that had deteriorated, but the lack of other people on the table. With warm cuisine as the focus, Ryo's cohabitation with Qilin is just about to begin!
