Better than most isekai stories, but his relationship with the girls is a little weird. If you're in a relationship together, it would make more sense to clarify right? Or is part of the appeal to have a girl on your arm, but not have to actually commit or anything? I mean when you're basically going on shopping dates with them, it feels odd the story skirts around the exact word "girlfriend". Also so far nothing has happened with the government, also weird that he's just a man from nowhere and they're like "lol okay".
