I recommend you to watch Michiko Kichise's Daughter of Steel, which is also a story about a female primary school teacher and a problem student in the class. The first season ended in seven words. The second season will be broadcast this year (there are many delicious loli. . . )
In addition, Matsu Takako's Confessions is recommended (it is a film for middle school students, so it is recommended because of its special shooting method).
