Honestly, this sounds dope
At least the concept of being able to dial up or down some aspects of her (I would love a more "yandere-ish" side of her, more than just "you stop meeting up with woman, am I not enough?" thingy)
Or make her go full on "i would die without you" (but i just left for 5 minutes)
Maybe the dev has somethings like this in mind, and maybe it's hard to make those at the same time he is adding a lot of content and making new stories, so we may get this in the 1.0 release and/or forward
