This game is variety of fetishes. Don't play the part that you don't like.
You know, I'm with you on that but...that's slightly different. CP, even if fictionalized, is really, really, really frowned upon and for a lot of people, the fact that this scene even exists is...appalling.
Also, the shota content from the first game was a bit of a blurry subject.
Zombie kids obviously wanted to eat Airi (which is available already in the dungeon of GH2, for those that missed it). So it's not straight up ero-content.
Normal kid from the GH1 was also kinda acceptable because it was an innocent kiss turned dirty if I remember. You know, growing boys having a bit awkward, innocent kiss with an older woman (as a thank you for example) that is pushing them away when they get too touchy is a bit of a movie trope even. Trope that is acceptable because it is an example what separates appropriate from inappropriate.
This new scene though is...problematic. I see no way to defend it when the time comes for Steam release.
For once, I'm curious what will happen from now on because it is an unusual content in a quite well known H-game.
