Honestly, I don't think that the husband is a wimp at all, because he is always supportive of his children, even if certain things don't go his way. I have read ahead of the story and it turns out that he isn't all that bad, it's just his environment and the people around him that influenced his behavior. He doesn't get violent, and prefers to resolve things in a civil manner, which I see as a good thing.
If I remember correctly, he initially wanted to break up or seek divorce from his wife, but due to him relying on her and her parent for much of the finance towards assets, he couldn't just back out that easily, since he would be on the streets if he did.
To add on salt to the wound, he is stuck in this cycle of betrayal, which eventually broke his spirit over time. But, his children try to help the family stay afloat, although the daughter may have a different reason and purpose than the son.
I think that this manga definitely looks promising, especially with the incest aspect and how the father will manage to get away from everything.
The author Tearontaron is my favorite so far because of the stories and art that they create. I was actually quite surprised that they were also an NSFW artist as well, which makes sense for much of their contents so far on both the official author's page and on several websites.
I would say that this manga and other stories that they created are much more tame than the ones found on the NSFW side of things.
