Takuma Setoda returns to his hometown to live independently, only to find the old house from his childhood completely uninhabitable — a total ruin. Flat broke and in need of a temporary place to stay, his childhood friends' families offer to let him rotate between their homes for a short while. Though one friend makes her disgust clear and strongly objects, Takuma somehow manages to persuade her. And so begins a strange, bizarre, and unconventional boarding life.
