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. **, 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.
