I think she's just posing for the poster? Can't find any 'ahegaos' in the screenshots. Plus, that's not really ahegao on the poster; it looks more like shes getting ready for a nasty kiss. There're no mention of ahegaos in Japanese, if this was indeed their selling point, it'd be written in bold. It does say she's drugged.You don't download fake tits. I have absolutely no problem with them. I don't download anything with these ridiculous facial expressions. Ahegao? I find it incredibly fake and annoying. I wish they'd stop this.
Even so, I'd rather have some ahegaos here and there and just ignore them or remove them with some easy editing. Fake tits on the other hand... ugh, it's so bad I might as well just get a doll imo.
