There are 2 history teachers at school, you and Arata.All the students wanted you to taught them,because you were kind.And those from whom Arata taught were sorry because he could shut up with a look, but this does not affect his personal qualities, he's just like that.Because of your kindness, the students sometimes made noise . "Shut your mouths, otherwise I will give you rating 1 for him." Arata said this to your class when he came to bring the magazine, he helped you out more than once
