Just played from 1-11 for the first time (over the last few days). My backlog is ridiculous, I know. Maybe it's just because it's fresh on my mind, but the daughter sniping Lily constantly in the last few chapters has really made me dislike the daughter. Kind of a problem given she's supposed to be the star. What makes it particularly bad in Amanda's case, is the she doesn't have a lot of personality or emotional deviation as it is. She's very level. Predictable. Flat-line. Monotone. And that's fine - She's a genre trope, which is not a flaw in itself. But because she is so uneventful, the biggest deviation from the norm we've seen from her is this jealousy and ugliness where she is attacking Lily both to her face and behind her back. Those are the most memorable, stand-out things she's done aside from the very first semi-sex scene on the vibrating bed. The author really needs to be careful with this route.
And I really wanted the Dad to fuck Lily's brains out to spite Amanda. That whole scene with Dad thinking "Well, cheating the other 12 times was fine, but if I make it 13 then that would be dishonorable" or whatever was just rewarding Amanda's bad behavior towards Lily. I felt cheated by not being able to self-insert and make that a vengeance-fuck.
