I agree with
@Haukka und
@cor3zone here. It is annoying how they always force the disadventage on the MC and NEVER allow him to use his strength. His Siblings never need to compete with him in a situation where he is superior. It is like the pride of the father as a knight is the pride of the family. Therefore the MC who has incredible talent in Magic need to be forced into a Swordsman.
Ok the MC gets cocky rather fast, but at this point it is only abuse. There is no education here anymore and normally the one who gets that treatment would hate the rest of the family.
Even though they hint, that they love Al, their actions never show that. It would be honestly the best if the guests step into it and give that family a beating (at least verbally) or the MC leaves that family, so that they realize what they do.
If there isnt a conclusion or anything I would label that story as bad (or even shit). (Maybe harsh words but that is how I see that)
PS: what I gather from the novel readers ... this will continue even into the future .... in other words the author sees something like that as a normal, fluffy and slow family life ..... what a giant bucket of bulls**t
