I think the answer is somewhat more ambiguous, and I think things should be clarified, so let's go through them point by point:
On the one hand, we see that she is now more focused on sex than on love, and that may leave her affectionate side aside, but that does not mean she does not love him. A clear example is the end of episode 12, where her husband tells her he loves her, and she responds by saying she loves him too, but then immediately tells him that right now she wants a dick more.
We also see that Miyu clearly hates small dicks, but she seems to make an exception for her husband, helping him in some cases to relieve his sexual frustration.
As the previous comment said, Miyu loved him at the beginning, but by chapter 8, if I'm not mistaken, she proposes divorce. This is due to a series of misunderstandings and events that may have contributed to it.
On the one hand, Miyu entered the industry to help her husband, who in turn could not devote much time to his wife because of his work, the typical NTR cliché. His wife misinterpreted this, thinking that he no longer loved her, and at the same time realized that her husband was watching her videos, and all this ended up developing until it ended there, with divorce, with both accusing each other of being unfaithful.
At this point, Miyu has changed and is the person we know from the last few episodes, a nymphomaniac and sex addict. Also at this point, and even before, Miyu realized her husband's fetish, who got excited watching his wife being NTR'd. So one way to look at it, from Miyu's perspective, is a win-win situation. She works at what she loves while keeping her husband satisfied.
Of course, there are many interpretations. For my part, I think that based on the simple premise of the NTR genre, anyone could think or may think that there is no love. However, there is no meaning or feeling of NTR when there is no real love. It simply loses its power. It's “exciting” because of the adrenaline rush or the feeling of losing something, but what's the point if they emphasize from the beginning that you've already lost it?
In conclusion, you can interpret it however you want, because in the end, the decision will fall to the author, and in turn to their fandom. Their fandom seems to be divided; on the one hand, they want to humiliate the husband, and on the other, they want to emphasize or develop the relationship further. Right now, all the author is doing is alternating or balancing things out so as not to upset either side.
However, if the author is faithful to their main ideas, an NTR work, removing the husband from the work would practically imply another genre, which would cause them to lose their followers because, after all, they are the ones who followed them for that genre.
For my part, I am one of those who likes Netorase, a netorare more focused on the couple's relationship.
This is my analysis of this work. Of course, it is only my opinion, but it is an objective fact that the author treats their relations
hip with ambiguity .
