This reminds me of a lover of my past workmate, a total dick both in and out of the work despite being fit and quite good looking, so succumb to the asshole that he treated her like a slave(an abortion made them break up eventually).
May be it's some kind of genetics but knowingly taking advantage of that just doesn't seem right to me, I guess that's one reason some families are on the verge of disaster along with alcohol addiction and etc.
Hentai eromangas are good spots for them to be kept fictional but shits happen IRL.
