Having played both endings, there's definitely something more going on.
In the LC path, Lydia i
In the NTR path, she's
In both cases, Zotje Onnozelaar (MC Mike) behaves like a complete idiot. Sure, it's a huge shock, the NTR most viscerally. But there is no reason to either run off with some SGs, or assault another SG, or get drunk in a torrent of self-pity. What he needs to do first and foremost is 1) directly confront Lydia there and then and 2) Go back to Stacy and AmRose, tell them what he discovered, and live happily ever after with them, after taking their horrible and humiliating revenge on poor Lydia, whom I never hated or disliked, and actually got to enjoy more and more as she started to mellow out. She was a breath of pure air amongst all the endless more or less mindless copulating (though with AmRose and Stacy it was never mindless but out of burning love and desire). In any case he definitely hasn't discovered the entire truth (if this is all the reveal of the mystery we get, it would be a huge disappointment after such a strong build-up). So instead of completely overreacting and giving up, he should be forging ahead and discover either the true puppet master or mistress, or at least the reason behind the whole app operation. So I'm hoping that the next updates will focus on tying everything together rather than 'just' providing 18 (well, 17 or 16 now I guess) endings for every possible girl combination.
