There are still 0 signs for me that she sees it as an adventure or something.
Clearly Aiden is polarized in 2 camps.
Those (me too) who see the humiliation and sexual harassment and therefore see Sophia as a victim.
Those who find Aidan great, since there is also a certain tendency to find humiliation and bullying great.
Both camps are strengthened by the fact that she also makes wet comments during the humiliations in addition to disgust. Nevertheless, I believe that the developer did not think it through to the end. Either ... or. Or as I wrote above in another threat 3. Choices. Goodwife, Filthy + (do it, with wet and horny-stuff) and Filthy - (do it too, but with disgust, loathing, trauma etc).
This leaves the No-Aiden team with only 2 options. Dylan Boarding School or Mafia. And Team Aiden simply doesn't need to choose the Mafia variant and can continue to violate Sophia in peace.
You are right in your opinion that Sophia sees the blackmail as a sexual adventure. There is, except for one scene, no evidence of sexual arousal when Aiden or Andre are directly involved in the actions.
But L&P always makes the moments erotic for Sophia when she interacts with people who are as innocent of her situation as Sophia herself. And with whom Sophia believes that a "no" would also mean "no".
One exception is the scene with Aiden and Andre, the gross sexual assault of Jennifer, where, if the player allows Sophia not to intervene, she turns away at the end with a mixture of sexual arousal and self-loathing. There should have been a high score of filthy points here - but nothing. Because in this scene, Sophia betrayed everything - her own moral standards and her profession as a teacher.
Whether Sophia observes the whole event or not doesn't matter, only that she learns about Aiden's blackmail of Jennifer is important.
Also, the scene at the meeting place of Aiden's gang is nothing to hear from Sophia except disgust, fear and shame. There are a paltry three filthy points to be gained and the whole scene seems to have no bearing on the blackmail route at the moment.
You can leave the situation/place in time (which I did) without changing the extortion route. For the moment!
Because of the completeness - so far the player only has to allow the Aiden scene during the 3rd task.
For me it looks at the moment as if the blackmail route can be played in a way that Sophia is brought into erotic situations by the blackmail and L&P lets her experience them as such. Of course, that doesn't work completely without coercion!
But the whole stuff with the fear, the disgust and the shame, which are the icing on the cake for some here, can be avoided.
