No idea what the dev claimed the game was originally meant to be but it's pretty much canon-balling into just trying to be the "most opposite" of AWAM it can be. Lots of sex, that may not even be really explained, the characters having no real moral or personality they stick to, etc.
It's like the dev thought "hey, there's a lot of pissed off fans of AWAM, I bet if I had an attractive housewife with a family and corrupted her into having sex faster, I'll get a large chunk of that games fans", and the dev completely missed the entire aspect of coherency, the fact that the build up can be as much or more erotic than the sex, etc.
If you're still following this you're about 3 versions ahead of me. I think version 2-3 was where I saw the writing on the wall with the 'story' already unraveling and the game rocketing down the "wife is a slut with no morals, even if she's supposedly had a decades long marriage and supposedly cares about her image and family" trope that all other female protag games do at some point.
