Mr. Red Nose

Ishihara's students suffer from serious illnesses like leukemia, kidney disorders, asthma and diabetes. On his first day at school, Ishihara wears a 'red nose' and attempts to amuse them but it only makes one of the students' condition worse.

After noticing Wada is in love with a girl in another ward, Ishihara meddles in his affairs and makes the girl attend the inhouse class. Contrary to his expectation, Wada gets angry and runs out of the classroom.

A new student, Chika, who suffers from diabetes comes into Tagawa's class. But the snacks Ishihara gave her start causing troubles.

Unlike Tagawa, the harder Ishihara tries to make the students laugh, the more he fails. To have at least one student like him, he makes an effort to get along with Tanaka, but she ignores him and throws her manga out of the window.

Ishihara decides to take his students to the sunflower field as an extracurricular activity to help them release stress. Meanwhile, Wada's health has deteriorated and when his father learns of this, he tells Ishihara to lie so that Wada will never know the truth. But then Wada's condition starts to get even worse.

Ishihara hears a rumor that Nanase is being recruited by another hospital and realizes that that is the reason why her attitude towards everyone has been so harsh.
