I agree, this is a more kinetic novel and I absolutely see why it is not your thing. But you can turn down a girl completely, and I don't know if this decision will not alter the story later on. But this is speculation.
And if I think back to the early VNs I played like "Runaway City" that qualifies as VN.
But unfortunately, in my opinion nothing or almost nothing has changed for the better and MC is still a character without any personality, who obediently as a dog performs all commands and agrees to everything without questioning what is going on around him, the same goes for for sexual scenes, in some cases he has the option to refuse but there are still scenes where he can't say no, and that doesn't suit me as a player because I want to control the MC and decide with whom he agrees to have sex with and with whom not.
I disagree with that. The MC asking a lot of questions and get them all answered.
He came to the conclusion to play a long. Which I think is reasonable in his situation.
He is not a Dog. Who is obediently doing everything he is told to do.
If you talk about the Dryads. It was hard to stomach at first, and this Trail of Fires was waaayyy too edgy for my taste too. And if the game would be completely like this. I would completely agree with you.
But in his coven? His behavior makes total sense to me. He is an apprentice or pupil. A Rebel schoolboy would be very cliché and not fitting from my view. In this game he struggles to find his place but come to terms with it and make the decision to learn.
To the Sex scenes. I believe there are two scenes which you can't avoid, correct me if I am wrong.
One is the first scene of the game, and it is his girlfriend.
The second is with Sura. And this is important. The character wanted it. Furthermore, it was his solution for a Problem. (This whole trail of fire thing is... You have to see it with porn logic, then it works. I found that unfortunate too, but it is this one scene.)
It wasn't like "Big city pleasure". Where a teacher drugs and rapes you and the MC is ok with it after that.
Everything else is avoidable.
