Cara is one of my favorite LIs so far, but unlike you, I'm a big fan of the daddy/daughter stuff. Surprisingly, though, Mary is currently my favorite LI, especially after her content in this update. Mary is the first LI to get deflowered by MC, and it was such a sweet and well-written scene.
There are very few LIs I actively dislike in this game. Not a big fan of Sue, due to her personality, but her scenes are hot. I wouldn't touch the woman from the warehouse with a 10-foot pole. Don't care for Alex, partially because of her tattoos, but mostly I just dislike her overly slutty personality/behavior. If that all turns out to be an act, and she's actually a virgin trying to hide her insecurity behind a slutty mask, then I'll give her a shot. Her tattoos aren't bad enough to be a dealbreaker on their own.
I'm on the fence with Alison, mostly because I don't like how she handled the situation with MC and Cara. She should have done the paternity test the moment she learned she was pregnant, and left Pete immediately after. At the very least, she should have told Cara the truth as soon as Pete died, especially since she knew how happy it would make Cara.
I really like Lucy and her daughter, but I am a little worried that MC's niece is a streamer. I hope she remains just a "gamer girl" streamer and doesn't devolve into just another overdone camwhore trope. I did not like when MC was thinking "please be OnlyFans!" Hopefully it was just dev joking about the trope, and not an actual red flag. Would hate to think MC is actually okay, or worse, happy about the idea of his niece being a prostitute.
