Tales of the Nurse's Room - S1.E5

Mr. Makino is a very popular teacher. He conducts a regular class for the first 30 minutes and then tells "really scary stories" for the last 15 minutes. The dean complains to him, "The other teachers are all doing their 45-minute lessons according to the rules. You should know better. You're an adult." But Mr. Makino has no intention of changing his style. He doesn't like the stuffy atmosphere of the staffroom, so he spends all his spare time in the nurse's office reading books. One day, Nao is resting in the nurse's office sick with the flu, and, through the curtain, hears Mr. Makino talk about his trip to Malaysia.
