Oh. I'm liking it. I mean, I don't have any prejudice against isekai fantasy stories, but it also means that I don't expect much when reading them.
But I like Esther and Toru's interactions, so that's engaging enough for me. Well, her design's lovely, so that also counts.
It may be annoying, extremely so, but this is fairly common in real life.
Anyways, I already got used to these kinds of developments, so I'm just glad he doesn't think with his dck.
