Hey guys! I'm looking for a manhwa/manhua/webcomic where the Mc is a loser, gets beaten up, and taken advantage of. But then he gets super strong (Does't have to be immediate, but I'd be fine if he gets super strong over time) and beats up everyone that did him wrong. And I'm looking for something on the more serious side, where the MC is actually savage, doesn't give a fck, and wrecks his enemies. Thanks!
