(Not yaoi) This may just be a dream, but the MC was a male kid I think and was taken care of by a woman. The MC lacks magic capability but then uses this forbidden magic that reveals that's he can be much stronger. I think the forbidden magic was from a book and was fire element. Mom/woman gets mad at him for using illegal magic or something. Honestly, I have no clue.
