MC won't marry a girl used too much by other men, incl. pregnant.
If a girl has zero hearts for MC, she's lost.
If that's the case, regaining back hearts is easy. Take her to eat her favorite dish again, and spam night patrols on her at the Inn. Hearts aside, even if the girls are used alot, do the marriage flags still trigger?
I have noticed there's 3 ero titles: Virgin, Non-virgin, and "Mother" (経産婦, actual MTL is "Multiparous woman", but it means experienced pregnancy before or something). Anyway, since experiencing pregnancy confers a permanent claissifacation, is that the flag ender for Marriage? I think intructions from the Dev indicate that. Which would be a bummer, again, for Netorase purposes. I would like to test it myself, but probably would take me a long time, since this game is actually pretty hard, all things considered.
Anyway, for the Ntorase kink, I guess I could have her be a slut and just not knocked up before to marry her, worse case scenario
Would be cool if Netorase is properly implemented in the future on this game (Right now, it's all NTR from what I can tell, as he doesn't appear to get excited when he catches the girls getting pumped at night by other dudes). Well, after all the bugs are fixed haha
