It's actually decent. Sure you can criticize, but the critism given here are either exaggerated or stupid. First and foremost, this is hardly a "copy paste" of solo leveling. In fact, solo leveling is kinda mid too, I'm a long term follower of that title and it only got popular due to art. It's also not your typical "reincarnated/transferred to a body" where the mc acts all dense and annoyed by people or having a deadpan expression. What I like as well is that the world building is like modern world with magic. Most mangas would just straight up isekai. It's actually a little refreshing but things feel rushed. Considering the way female characters are introduced, it may have that "multiple girls liking mc" kind of vibe, but if you actually realize it, it doesn't seem likely to happen. Why? Well, it's not his body and we can see the mc is unsure of the thing regarding his relationship with his friends and his identity, there is also the fact that this isn't your typical magic world kind of shit so polygamy may not even be a thing and the mc already seems to have someone he is looking for.
