I really wish I could've enjoyed this more than I did. But it suffers from the same sort of power fantasy issues I see with most isekai and basically every manhua I've ever read. Within the first 30 chapters or so, the protag becomes so overleveled that he never really faces a combat hardship again. It's probably just a me thing, but I find it much more interesting when a protag fails and has to find new ways to grow and adapt, or get help from someone else with a different skillset to overcome the latest trial. Jinwoo is just another in a long line of protags who's special and powerful and right all the time and everyone else is a liability at best.
