Early the next morning, Kaoru keeps Sentaro from abandoning his house for good. When Sentaro's foster father reunites with the family, Sentaro feels satisfied when receiving from him an expensive fountain pen, confirming that he treats Sentaro as his own son. Kaoru and Sentaro ask Tsutomu to perform with them for the upcoming school festival, and they later convince Ritsuko to be the vocalist of the group. At the night before the festival, Sentaro, realizing Kaoru forgot some sheet music, he sets off to deliver it to Kaoru by scooter. The next day before the festival, Ritsuko tells Kaoru that Sentaro got into a car accident the night before, prompting Kaoru to rush over to the hospital. Sentaro is said to be fine, but his younger sister Sachiko, who was riding with him, suffered a head trauma and is in critical condition. Kaoru comforts Sentaro on the roof of the hospital, but he wakes to find that Sachiko has awoken and Sentaro has run away. Kaoru tries to comfort Ritsuko, but realizes that Sentaro will never come back.
