Surprisingly sweet for something tagged as incest. This would be an incredibly healthy relationship if the main characters just weren't related. The biological relation's actually pretty distant, though, since the "uncle" isn't actually either of his parent's brother (I think). Still a bit awkward every time someone refers to them being related though. However, they really do love each other, have almost always only had mutually consenting sex (the only time they didn't one of them was sick, and he didn't have that much of an issue with it), and they have surprisingly solid communication. If something's bothering the... housekeeper... (I'm not gonna say uke bc I hate that term) usually just stresses a bit before spitting it out. The novelist tends to just take whatever in stride, and if he finds out something from another source he immediately seeks out the housekeeper to resolve the conflict. It's honestly really sweet, and reminds me of a healthier Junjou Romantica. (bc let's face it, that relationship is many things, but healthy ain't one of them.) Anyways, if you're looking for something a bit milder than normal but still really hot, I suggest reading this!
