Synopsis
It was a girl in the next class who decided to stay with us. One day she suddenly came home with her mother and didn't know what she was thinking, and her quirky face was so good ... I don't like it. I think they don't interfere with each other. Where do you go out at night once in a while?

Mother and I have changed from old to new homes, and this time we had children from the same school. Have them cook, share the housework, and care about me going out at night. But even if I was told where I was at night, what should I say? I'm just meeting an acquaintance.

A faint and fragile story of two high school girls who suddenly lived together one day.
