I agree the cover art is the mother of all bait, but seeing Cheating and Het should have given all the warning you ever need to bury this under a spike forest with "This place is not a place of honor" inscribed.

Contrariwise I don't see how the people who were not immediately upset can possibly defend this for it's artistic merit. The story is rough, poorly paced and frankly doesn't make sense. The metaphor on women's smell vs. smoking peters out, characters display mood swings only explainable by chemtrails being real and made of oxycodone, and the balance between plot and porn disfavours both. (I'm not qualified to judge graphic erotica, but with stiff and unattractive characters, the latter's quality probably isn't.)

Overall this felt like reading some incel's scribbled storyboard (butch lesbian fucked into becoming comphet submissive housewife) without later refinement. Looking East's take of dark humour/tragic irony is the only thing I could hold to this manga's credit on an exceptionally good day, and even then 'tis a mere "meh, not my kind of tragicomedy".

TL;DR: Beyond your gut feeling that this is male bovine excrement, it's also objectively flawed.
