Mothers of friends - a forbidden class visit day, an interview with three people of suspicion - related to Orihara Nami HORIKAWA Hazuki Naho

The three children of Orihara, Hazuki and Horikawa were asked to stay until after school for some reason. After school, the homeroom teacher told me that his three sons were too bad to graduate this year. The three of them, who had run out of trouble, were tempted by the color scheme and could barely even take a follow-up test. However, there is only one person who can graduate because it is a special case. The three mothers, who wished to have their own sons graduate at all costs, each tempted the other two sons and began to interfere with their studies. you don't know that we're doing the exact same thing with each other.
