One day, Yuko stays at Haruko's house to attend an art institute for the summer. Yuko is the daughter of Haruko's old friend Tomoyo. They haven't spoken for many years prior to Tomoyo reaching out to Haruko to ask if her daughter could stay with her for the summer. Haruko and Tomoyo have an uncomfortable past.
