The episode begins with Yasuda-sensei being woken up by a student and rushing to class. In the classroom, the students, including Hori and Miyamura, seem distracted by something, which turns out to be Yasuda's hair, styled by some girls while he was asleep. This leads to a humorous interaction between the students and Yasuda.

Later, there is a comical scene in the teachers' lounge involving Nakamine-sensei and the key to the resource room, which he keeps misplacing. Yoshikawa helps Nakamine-sensei patch a hole in his pocket, leading to some playful teasing among the teachers about Nakamine-sensei's popularity with the students.

In the student council room, the boys discuss the importance of height and appearance, resulting in a humorous exchange with Yasuda-sensei. The conversation then shifts to Yasuda-sensei's personal life. The students mock him for not having a girlfriend and compare him to Nakamine-sensei.

Back in the teachers' lounge, Yasuda-sensei is scolded by Terajima-sensei for getting too chummy with the students. The students then visit Yasuda-sensei in the counseling room, where they continue teasing him about his personal life and bring up the cake from earlier.

In the student council room, Hori and Sengoku fall asleep and accidentally get locked in. After a series of comical interactions, they are eventually rescued by Yasuda-sensei and Terajima-sensei. Terajima-sensei then reprimands Yasuda-sensei for his inappropriate behavior, leading to a humorous exchange between the two teachers.

The episode ends with Hori, Miyamura, and Sengoku discussing the incident and Yasuda-sensei's behavior. They then witness Yasuda-sensei acting strangely in the hallway, leading them to assume he's been brainwashed by Terajima-sensei.
