Hi guys! I remember that I once read a manga/manwha but I can't remember its name.

I remember that the MC was assigned to a mission: he had to discover if someone's son was bullied or not. I remember the MC being a very powerfull mage. It turns out later that the bullied guy is bullied because an accident made him appear as a monster. I also remember that he solved the whole thing by befriending him and putting the bullied back to their place.

That's all I can remember so far! I think it was a manwha or a webtoon.
Thanks in advance!

Well that was both quick and accurate, thank you so much!
