After suffering the wrath of the dorm supervisor yet again, Kuroko seeks revenge and decides to follow her while dragging Mikoto along. They soon follow her to an orphanage for Child Errors in Asunaro Park where, to their surprise, she shows a kinder side to the children there. After spotting Kazari and Ruiko, who are helping out with their teacher Daigo, the girls realizes that the dorm supervisor is in love with Daigo. Hoping it would change her attitude, Kuroko offers to help her get the two of them together. The next day, the girls help take care of the children while the dorm supervisor and Daigo makes a birthday cake for one of the orphans which fails as she is too nervous. As they buy a birthday cake and celebrate at the orphanage, an earthquake kicks in and the dorm supervisor rushes to protect one of the children, where she is praised by Daigo. The two later go out for dinner, where Daigo asks the dorm supervisor if there is anything wrong for a younger man marrying an older woman, which she and the girls interpret he wants to propose to her. As the girls dress up the dorm supervisor for what they think is joyous moment, she meets Daigo and learns that he's actually planning to propose to the older caretaker of the orphanage, and decides to let him be happy and just be friends. In the aftermath, the dorm supervisor returns to being her normal disciplinarian self.
