Morishita has good grades, but on a class where everyone is an excellent student, his grades where bellow the average. Her homeroom teacher Tsukishima Kyoko was particularly strict on him, and not only about his grades, but even on his daily life. Morishita was very stressed between the difficult studies and the harsh teaching, but he had someone to help him, she was the assistant homeroom teacher of his class Shirakawa Miwa, a kind, maternal woman who understanded Moshita’s circumstances and was always on his mind.
