So an Isekai type story that focuses on the rebuilding of a society, does make for good and creative story telling. Sadly this story devolves into boring and obvious Isekai tropes. The time frame is never fully explained and the story just diverts to other things going on in confusing manners. Most of the characters are rather forgettable. The arcs are ok I guess, nothing to talk about. The harem trope? Doesn’t make sense. Like what the MC does one nice thing for a girl and they suddenly fall for him and want to have his babies? Realistic. All in all don’t feel bad about dropping this while you still can
