Another person who failed to read the story and should go read solo leveling.
Is this your try of a "clever" insult? (btw I actually tried reading it some time ago because of the hype but abandoned it after the first chapters)
Where did you get the idea he was a pathetic loser from? He had a hobby and actual losers were looking down on him for enjoying it so much he even brought merch to work. He didn't work in black company. He didn't die from overwork either.
Maybe saying that he lead apathetic life was too much but let's have a look what is shown in the first chapter. What he did was work, play, sleep, repeat. At work he didn't interact with other people, even in the game he appeared to be a loner who looks down on others. He was bored of his real life (that's why I said "pathetic", maybe "unfulfilling" would have been more appropriate). That's why he tried to escape into the world of the game. Now he is in the game and his only goal is to prepare himself and his family (originally it was just his sister) for the big event. Yes, I get why he acts like he does and if you read my comment properly (maybe you read solo leveling before reading my comment) you would know that I didn't criticize the whole story but single points and the pacing. What I criticized wasn't him not becoming the protagonist but solely him (again) avoiding any social contact except his family. Even if he avoids the game MCs because they are important for the main event he could at least interact with other mob characters. (since the last chapters he starts interacting with Risa and her friend but that was initiated by Risa)
I'm not going to explain why he isn't doing that because you should have realized why he can't do that without risking his and his families life. He's not OP either idk where you got that idea.
As mentioned before I get why he acts like he does but I don't like the way it's presented and the pacing of the story. The school arc where everybody looks down on him in some way and he secretly levels up is too long. You can actually skip many chapters where there is no progress in the story at all (just him getting "NTRed" by his "fiance" (in the webnove you can see that this actually hurts him put he suppresses "his" feelings for the sake of the story plot. On the other hand, he says that he couldn't go for another girl due to his game character, which makes him effectively asexual).
Maybe he's not OP in the sense that he is not the most powerful being in the game, but at this point he's probably far stronger than the hero and his party and many other pupils of the higher grades who look down on him. Regarding his skill "gluttony" (which makes him not invincible but pretty strong) and the fact that he got isekaied into this character you can assume that he will have some special role in the further plot of the game (maybe with the people who represent the other deadly sins).
Solo leveling is rotting your brain.
Again the insult? You really should grow up. I'm always willing to listen to other opinions, and I would actually be happy if you could explain your point of view but with insults we both will gain nothing. I'm not saying that I'm an expert (just read through the manga once), I just described my impression of the manga.
To sum it up, I didn't want to deny your favourite story as a whole, I just criticized some points who could be improved (in my opinion).
It's sad that nowadays we life in world where people just think in extremes. Just because I think the progress in this story is too slow doesn't mean that I'm into speed OP stories without much content.
There are many hints for great developments in the story but (in my opinion) the pace is just too slow: you get a hint for a development, then there are some chapters who just feel like fillers and then we get to the next hint without real development. (I hope the manga continues to being faster than the webnovel).
As for the MC, I would like him to show some kind of personality instead of acting like a robot. I'm missing some character growth.
My interpretation of MC: He lived a loner life and was bored of his real life and the daily rut. That's why he escaped into the world of the game every evening making it the most important thing in his life (not just a hobby) because in this world he was one of the best and not just one of many (mob character). Now he is in said world and he lives again a loner life with a daily rut (preparing for the upcoming event). He doesn't act/shows on any feelings (except his wish to survive and protect his family) and all his actions are dictated/limited by the main story plot as far as he knows about it (there is probably a hidden story in game behind Butao but we'll need probably need 100 more chapters to come to this point). That's an interesting idea but it makes it boring to read without any personality shown (e.g. making up with characters his character hurt before isekaing)
PS: Sorry for the long comment, but I had the feeling that my words would be twisted again otherwise.
