*Spoilers till chapter 81*
All in all it's quite decent, but a bit inconsistent. The names and characters for the most part are hard to remember or just unmemorable. The MC seems to change personalities on the drop of a hat. And for the most of the series at the start, he didn't want to bang just anybody, but by chapter 81, he just randomly fucks some random girl someone arranged for him. Quite a change of policy. Also, the art quality drops considerably around these chapters. Just terrible. The other reviewers are exaggerating. This is not even nearly the best Isekai. Not even among Manwha.
