A typical day for Toshimori Sumimura, Yoshimori's youngest brother, starts as he heads off to school. Two of Toshimori's friends, Gaku Mikawajima and Taichi Komagome, get into trouble for not doing their homework, and they later beg him to tutor them at his house. Toshimori is reluctant but eventually relents, though making up a story about Yoshimori being very frightening. However, when they arrive home, Yoshimori greets them while wearing his baking attire. It is mentioned that Shigemori is on a hiking trip with a group of senior citizens, while Shuji is meeting his editor for his novel. When Gaku and Taichi wander in the house, Toshimori accidentally creates a barrier and injures both of them. Tokine later visits bringing some curry over for dinner, but after she encounters a cockroach, she spills it all, with Toshimori taking the hit. After the three boys take a bath, while Yoshimori and Tokine clean up the mess, Gaku and Taichi say goodbye as they walk back to their houses.
