Sorry it's not really much help! Would like to know what you're looking for though cuz it seems interesting especially after I read Weak Hero TT loved that story a lot.
Okay so ive searched everywhere and i still cant find this manhwa that i read a few months ago and ig nobody on reddit knows it either so if you know plz let me know been looking for an hour already :(
I dont remember much but its about this guy that goes to a school where a lot of people want to fight him I think but he befriends this 1 guy and together they fight bullies but the group increases everytime and then they make some sort of forum for guys that are bullied to request for help and they go beat them up and i dont remember a lot but 1 super bully gets kicked out and then the mc becomes th leader of that school and then he transfers schools fo go become #1 at this new one wnd this is where i stopped (wounds like weak hero but its not) plz if you know
