Review Detail of Credo_A in Hogwarts : leveling up the world

I read until 19 chapters, I decided to drop it because this MC fvcking reveal his secret that his a otherworlder to a bunch of powerful old wizard and some of them is antagonist in the world of harry potter without much power to protect himself that's totally idiot decision from the author, sadly I like the idea author making but that scene destroy the possibility for me to read anyway this one is not bad it's just not my cup of tea.
