For an Isekai, it doesn't really refer back to the real world much besides perhaps 1 or 2 flashbacks that last about 1 panel and his job. The only thing that really sticks around is the fact that the world he is in was a Manhwa he himself read. This doesn't bother me too much since it's basically the norm with Isekai stories to have basically no ties to their past life.
As I mentioned, it gets very unoriginal as time goes on. I mean from the begining he has a "game menu" with skills and levels so that's already extremely overused in Korean Manhwa but whatever I can deal with that. What annoys me is that he's meant to be some average guy and isn't even the protag of the Manhwa he read.. however he very quickly becomes more powerful than the actual protag of the story world. The story also devolves into focusing more on fighting monsters etc than what the title would suggest the story is about.
