I'm not sure if it's Manhua or Manwha, but I think that it's manhua, it's colored, and that's about all I can remember

So, in the beginning, the MC is weak and bullied, he's scared of standing up to them because they would beat him up even more. He tries to find a place where he can learn to fight, but after one day he gives up because it was hell.
Later he is out with some girl (just talking I think) and some bullies find him, they r*pe the girl in front of him and he has to watch because he can't do anything, that pushes him to go back to the master and learn how to fight.
The master discovers that the MC is something like Natural Fighter, or along the lines. But because of his personality, he can't still fight so the master puts him under hypnosis, the hypnosis works like this, when he has his glasses on he is his normal self, but when they're off he becomes something like battle junkie. MC then begins to truly fight against bullies, they're fighting in some kind of prepared space with a camera and it's designed for fighting. He eventually defeats multiple bullies and then he has a fight with his bully from school. he defeats him and they later announce him as the strongest loaf bringer (or something along the lines).
That's about all I remember 😔
Thanks for any help~
