some see sis and vicky having sex (rekindling their old relationship) w/o mc knowing it as ntr, originally it was unavoidable but now it can be skipped.
other thing which caused upheaval was twins reveal that they do escorting.
I don't care about the first personally, the MC fucks anything that moves, and NTR is just slang for insecurity for most people. I certainly didn't feel humiliation or arousal from a feeling of humiliation....
But the twins, that was a gut punch. What is it with this Dev and throwing in the sharing content at the last second? I don't think its just a high level supporter, this feels more like a fetish they life to indulge in (which if so, kudos, enjoy your kink). But 1, it really shouldn't have been hidden, that was stupid. And 2, it's written so so poorly. If they are so proud and sex positive about being hookers (their own FATHER is their pimp), they shouldn't have any problem with their little sis being recruited. But instead, they treat the world's oldest profession like its totally natural, and then literally two seconds later, as it's going to destroy their sister.
Now, this level of hypocrisy would be fine if the Devs actually wrote it in to their characters that they unconsciously HATE what they're doing, that they are actually unhappy and feel like they're beyond saving, but its not too late for their baby sister. But it's not written like that.
Honestly, the twin reveal did what a story should never do, killed any interest I have in their character.
