I don't know if I didn't miss something, but for me it look like the MC have a superiority problem, thinking thet since he is one of the heros son, he have to be the 1st and beat everyone... He's 2nd in the school clasment, just behind the princess... And he react when all the fools behind him (the students) say something about his father?
I want to see if it will change in the next chapters, but if it don't stop it will be boring really fast...
