well, in Asia appearances are very important as well as the family structure (I do not know how to formulate it correctly but the fact of having "a perfect family" without spots). And the fact that he takes care of household chores can be a source of mockery for other boys, since it is a task "reserved for girls" (╯°Д °)╯╧╧. And being friends with the professor = frowned upon, or can create false rumors of favoritism Σ(  ̄□ ̄||). I think he doesn't want his sister to be harassed because she is related to him.

It’s just mean you are in a fairly good environment. M 20 this year, and when I was in high school I experienced harassment and also something similar or worse.
When reading manga, you really do have to think about who is the one drawing it, what kind of time period they lived in that they try to portrayed.
Of course we could all tell it is a fictional work, and does contain exaggeration, but it does have to based somewhere.
It is nice whenever I read a manga or novel and I don’t understand why how some people could be that stupid n cruel. Even tho there still exaggeration, but I still am very grateful for not having to ever encounter or experience it because I can imagine how hard it is to struggle...
....i dont understand why any of these situations are supposed to be kept secret... secret as a housewife? He's not really though... why is being twins a secret? Why can't you be friends with a teacher? So many questions!
