From a character perspective, I'm a bit disappointed that Lydia apparently turned out to be responsible for the blackmail, as I just got to like her a bit in the last few updates. But at the same time, this just means I can focus more easily on my actual favorite girls, like Lyssa.
The NTR path scene was pretty fucking damning, especially as she refused to have sex with MC until this point and also seems to enjoy specifically engaging in play she knows MC wanted to enjoy with her. She might even get off on that idea, that she's denying MC without his knowledge. So I cannot think of any excuse that would not make me take extreme revenge on both her and Pete in the future. Though I wonder how she plans on continuing the game with her kicking MC out just beforehand.
