Yumiko, a homeroom teacher who is worried about a student who is not good at studying and who is a regular student with red marks, has come to visit her home. However, her parents are out and they have to have an interview alone. Since this is a rare opportunity for her, I ask her parents if they have any worries that are difficult to talk about. As her homeroom teacher, she must save the troubled students. Renewing her determination to be her good teacher, Yumiko teaches her students how to kiss adults.
