Shin'ichi Namura (名村 慎一 Namura Shin'ichi), affectionately known as "Na-chan" by his students, is a former Toryo student who returned to his alma mater as tennis coach and English teacher. He develops feelings for the student Meiko Akizuki, which are reciprocated. However, because she is a student they must keep their relationship secret. The relationship is eventually discovered, embroiling Namura in a big scandal.
Finding his position at Toryo untenable and fearing he'll be a hindrance for Meiko, he resigns and returns to his hometown of Hiroshim] in order to study real estate and take over the family business. Namura tries to push Meiko away from him no matter how much he loves her, thinking that he cannot allow her future to be tainted. Ultimately, Meiko proves him wrong, and they reach an agreement: as soon as Meiko graduates and turns 17 (the age at which she can marry Namura without her parents' approval), she will come with him to Hiroshima not only marry him, but also to study literature and become a writer. At the end of the series, the agreement is filled and they marry. In the anime television series, Shin'ichi Namura is voiced by Tōru Furuya in Japanese and Jack Aubree in English.
