Honestly, even if it's Engrish giberish, you bitches hating on the people that took the time to do it are a bunch of arseholes. Yes, no shit, it isn't suitable for a fucking English exam, but the scanlators are doing this for free. So stop speaking shit about the quality of English, and maybe focus on the content, because it isn't that hard to decode if you can speak proper English.
This has a good start for an isekai, but the problem is that it's an isekai. If the author can hit the drama strong like other editor-san manga such as Hitman, then this could definitely do well.
