You can absolutely romance Clarice on the good guy path and it will result in a nice scene and confession of love towards the end of the current build. It was worth the wait. Even though it only results in a somewhat tame make out session (at least Clarice is nude), but everything else would not have made sense for Clarice.
I did not check out all options (I usually only play the good guy path), but I think Elaine is the only LI where you have to make a bad guy choice if you want scenes with her. I remember a scene in the kitchen where you can only do stuff with her if you pick the bad guy option (her husband is in the living room nearby). Given Elaine's character I think it makes sense that a bad guy can score with her while a good guy will avoid her like the plague and go running for the hills.
Pamela... zero scenes so far but things are heating up on a pure love / good guy path. She has seen the sex tape Susan has made and is very much interested.
Yeah, even though the WT mod suggests to go the bad guy route with Clarice, I'm guessing its because it prioritizes lewds over everything else. It did the same thing with Sarah, which I had heard her route is better playing the mostly good guy path with her and Lisa. Getting back to Clarice, while it was hot and exciting seeing her lose her inhibitions every time she was around the MC, I honestly felt like a piece of shit impersonating a priest and corrupting her to do something she should decide to do (follow her heart and desire) instead of being manipulated into it.
I went bad guy with Elaine since, well like you said its pretty obvious that's who she is deep down, going so far as to convince her sister to start an affair with her notwithstanding. I do wonder if we'll have any true kind of relationship with Elaine other than just sex, unless all she wants is just sex, sex, and more sex with the MC and her sister.
As for Pamela, I started out on the good guy path with her, and despite being very tempted to take her up on her offer for sex on top of whatever other benefits she is offering for our help with Clarice, I've stayed on her good guy path and her watching Susan and the MC having sex and watching their sex tape has really turned her on. I think we'll finally get some action with her, hopefully some romance/love with lust, but I am tempted to see what I missed if I had chosen the bad guy route with Pamela.
Last point I want to make is I hope Iris and Beatrix can come to an understanding regarding their love for the MC. It's obviously hypocritical for Iris to react the way she did to Beatrix's confession, given Bea has been in love with her brother for even longer and she was just as ecstatic to admit her feelings for him and finally have sex with him too. I found it funny Iris claimed she has no illusions of changing her uncle and loves him for who he is, even if it means sharing him with other women...except if one of the other women is her aunt, lol. Truthfully, I just assumed that was her being immature and in shock about the situation and why she ran off, but for her to scream NO! over and over, was a really poor reaction. Given how everything is shaping up to be a harem, I'd hate for this to be a situation where we have to choose between Iris and Beatrix. It's super fucked up what happened with her mom and the mental anguish it has caused her and her father, so I guess her being young and in a fragile mental state is to be expected.
