Because, let's be honest, even if it wasn't TECHNICALLY a cheating scene... It was a cheating scene :p
It was supposed to give you emotions like that.
It wouldn't be such a problem if they just put a warning for that type of content.
Okay, fair. It does definitely feel like that from what I’ve seen from others. I just never felt that feeling during that scene. Literally all I thought was ‘Ooo~, Amicus and Neferu~! Oh shi-’, but I also never felt that romantic attraction to Amicus like most others, so I guess I just don’t see the true effect it had on most. Also never felt that “post-Adastra-depression” as others have, but that’s also probably just me.
