It's somehow fun and the time feels comfortable.

The family restaurant after school is the only place I can relax and enjoy myself since my parents remarried and I no longer have a place to stay at home. I met my classmate, Kasemiya Koshiro, at the family restaurant. She is a beautiful, isolated girl who doesn't get along with anyone.

Apparently she's also having problems with her family.

From that day on, the boring time at the family restaurant became a fun time where they could complain to each other. At the family restaurant after school, the search for the reason why the two of them didn't go home began again.
