Author got greedy. Read til like 290 then drop it. At this point hes begging people to go to his patreon. ..................…...............

Wonder if people actually like this story enough to pay, cause he already lost all his readers here.

I hope this comment is a joke because sane people aren’t going to get jealous of fictional characters. The real reason people don’t like harems is that they are more often than not, accompanied by terrible character development. Most authors struggle to really flesh out the personalities of several love interests and this basically kills the novel. On the other hand, authors can focus on developing one love interest and really give them depth. I’m not saying to not get invested into whatever content you’re consuming, but if you feel actually jealousy of an anime character, go get some help.

It's pretty good right now. Still fairly new so there aren't any crazy developments yet. Power scaling is kinda weird when talking about the world but I blame that on DxD itself. The LN has some of the worst power level explanations and scaling ever. It's too inconsistent in canon so you can't really blame the author for his own interpretation.
