If I remember correctly, you can help her up, but you have to categorically refuse to sleep with her the first time. Later there is a repetition of this situation, but then Frank is prepared.
I share your opinion about good and bad AVN, I also have my personal favorite authors and those that I find rather less good. Clever Name Games is one of my 4-5 favorites. Here and there you can see that there is still potential for improvement, but at the same time you can see an improvement compared to the beginning. For example, I remember a movement animation with Abby (?), which at least to me seemed very robotic or like on an automatic turntable. I think CNG didn't use something like that so actively afterwards and I just assume that CNG itself wasn't that happy with it or a patreon noted that.
Frank as the apparent main character (I have a hunch that actually Becca is the main character and we're playing a "corruption plot" in which exceptionally the player is corrupted, if that's the case and you're reading this CNG, deep respect, that should be stylistically quite innovative) is definitely a more sympathetic character compared to other characters who slip into the role of the father or paternal figure. I know of at least 2-3 AVN where the protagonist is either the father or a paternal figure and the father would either fall into the category of predator, the plot is rushed through too quickly for me personally and I feel like the character development of the female characters is getting short shrift and it's hard to see them as anything more than fetishizations or what was very new for me: the plot escalates in an absolutely new direction and you get the feeling that the author has no idea where he's actually going with the plot.
From there CNG actually does a lot right for me: The pace with Becca, Abby and Lilith is actually well chosen for me. At 0.12, Frank is actually a bit exhausting. His inner conflict makes sense and actually makes him sympathetic for me, but 0.12 is then also a bit exhausting for me here. In this context, I would like to see a bit more interaction with the masses. I respect and accept when CNG interacts more with the supporters, but it would be quite interesting for me to know if CNG here actually only wanted to troll the people who criticize Frank's inner conflict quite harshly and unconstructively. At the same time, I think that quite interesting dialogues with people who find CNG's AVN good, but do not have the money to support him, such as my person. For example, I once analyzed a certain sentence of Becca (which I won't mention here because I don't know if you already know it) and in the current update Becca explains it again and my personal assumptions actually coincide quite well with her remarks. Therefore I would like to know, for example, what CNG thinks about what it says about me that I have analyzed it relatively well. But as I said, I respect and accept CNG's decision in this regard, even if I find it somewhat regrettable.
As a conclusion I would say so far Becca and Lilli are my favorite characters: Lilli is well written in my opinion. Becca, on the other hand, is someone with whom I, as a player with some meta-knowledge, would be happy to discuss her plans, if only to find out how far I'm right and where I'm wrong.
