Tachibana is famous as the absolutely powerful PTA president of a certain school. However, on the other hand, she was strict with the teachers at the school, and her unreasonableness towards Tanaka-sensei in particular was flagrant. Among the bottom scum, Tanaka, who has an even stronger self-esteem, gets a smartphone at a certain place. However, I was also skeptical. The next day, she came to Tachibana in broad daylight to make a connection. Apparently about her son's smartphone.
