Ah the classic foible of a dumbass writer trying to write a smart character, only for them to come across as an absolute dumbass as well. Throw in bland unlikeable characters, generic ass plot, 0 world building, or really anything of quality period, and you get the archetypical garbage isekai.
If it was at least sexy it'd have some merit but it fails on that front as well. Only worth reading if you are looking to kill some braincells.
