Junior high schoolers Sudo Ai and Sosuke Ito live together as a patchwork family in a small town in Hokkaido, all thanks to Ai’s mother, Yumi, creating an environment of love. Bullying and the harsh environment cannot pierce that safety until Yumi dies. Cast adrift, the kids are separated, Ai is taken to Tokyo by her father, and Sosuke is left behind.
