The problem is, even if you reject the intrusive thoughts and actions (as stated above), Azel is still quite needy and touchy with the MC, which If I'm being honest, I find the whole needy, huggy and kissy thing quite annoying and that's my dilemma when playing WVM, some people like it, others perhaps, like myself, doesn't, but what can we do, so it's whatever.
And to be fair, after the MC found his biological family (quite literally), I thought Azel perhaps would've found her groove back into a normal life, taking a job again and keeping herself busy, but then we had the whole (I don't know my place anymore) from her and we get the whole "let's stick together like glue again, because..." and we're here. But then again, you already have your biological mother, on paper and from everyone's perspective on the game, Azel isn't your stepmother anymore, although the MC feels like she is, but now incest isn't a thing FOR AZEL, I think the story could branch out and break the incest-restriction by maybe transfering the papers back to the MC's biological mother, and let people finally date Azel if they want to, it's not like they're blood-related.
But again, I'm not into incest and I myself find Azel quite needy, so what the fuck do I know.. Let people bang her if they want, just bend the lore a bit and get rid of the whole family drama with MC and Azel, leaving them free to date if they want to, I don't know.
