Trash story.
MC is bland to the extreme and somehow having the magical OP power of "I will suddenly be great at anything I need to do" makes him less interesting.
Antagonists are boring and one-dimensional because they exist only to say that the MC is trash and therefore he sucks at everything even as he's succeeding without trying. And then when he bests them all they do is throw a hissy fit, storm off, and do exactly teh same thing next time around too. Nobody learns a lesson and nobody comes off as clever or intelligent in the slightest. Plus then you can add in the cliche "princess of the school who everyone adores but treats like an object of worship instead of a person is secretly in love with the MC but he's too dense to notice" and the gaggle of other girls who all end up fawning over him while the guys stew and get angry that the "trash" is getting attention and it's just.... dumb
It's the shallowest, laziest cliche crap imaginable. There is literally nothing redeeming about this because every chapter is basically the same thing (antagonists try to trip up the MC, he beats them without even trying or recognizing that they're doing anything, if there's girls they swoon, if there's guys they stew, and everyone sets up to do it all again next chapter) and even the mechanics of their RPG verse are so vanilla that they're uninteresting.
