I mean a guy enters a game system in his world that allows him to get stronger, yeah we do actually see that quite a bit in a shit load of stories, what pissed me off is how the main guy right now looks like a carbon copy of jinwoo at the beginning of solo leveling and that the guy in the cover looks like another carbon copy of Jinwoo after he's leveled up, mfs are literally twins, the only differenced here is that jinwoo let's himself get killed while this guy gets thrown as bait and while jinwoo only got the powers of a monster (monarch) it looks like this mc actually becomes a monster
“it looks like so-“ *gunshot*MF SHUTUP ITS A COMPLETELY DIFFERENT STORY .
