Also for reference I'm a guy. Gonna be honest what distinguishes Josei from Seinen, Josei doesn't shy away giving guys punches between their legs....Shoujo is even more devious in my opinion and the fantasy of girls is a nightmare for boys luckily when genre demographic goes up so do cringy gender based fantasies also mellow down a bit.
What i mean by girl based fantasies that can be hard to swallow for guys:
1) You current girl introducing nonchalantly her exes.
1.1 Sometimes they are clearly superior in many aspects (That's quite a low blow for the current guy. Also the problem stems that while you are with someone you try to think that your relationships are exclusive and intimate and meeting your partner's ex'es is hurtful (for any gender i think), since it decreases exclusivity with your partner
2) Having multiple guys proactively flirting with a girl while still engaged in some sort of relationships (dating or marriage)
2.1 Sometimes if not majority of times no active rejection towards those flirting guys
There are other points but currently they are not related to this manga and are not worth mentioning (1.point was the introduction phase and sadly she didn't even acknowledge what the problem is and 2.point him openly declaring his intentions and even saying that he communicated with her parents while she didn't state any boundaries which implies future events when he will overstep boundaries and she will not stop him.
My prediction: During midpoint, they will have good days and bad days (fillers). Meeting with the parents will go bad at first but he with his kind heart will melt his mothers(or fathers) heart and will even improve her parents relationships. Her ex doing a lot of stuff to sabotage them and even succeeding almost only for her to finally step up the emotional intelligence game or maybe MC finally growing some balls. There might be even redemption chapters for him when he will understand that they are meant to be together and he could not provide the same happiness as MC.
Since this is "Josei" i doubt it BUT there might be a female rival coming to snatch MC in order to make FMC grow as human (and understand her feelings a little bit) but even if it will happen since it is Josei the tribulation will be easy and quick in order not to damage motivation of girls who are reading this.(Some seinen and shounen authors do the opposite and quickly fall since NTR is fetish for a very small minority)
They will divorce! BUT this divorce will be only to make MC happy aka her remembering that MC loved the stories of romance between grandparents and re-marriage serving as a catalyst for "NEW BEGINNINGS" since by this time she would become at least "half human". (Or maybe mc will divorce her after she finally realised and told him his feelings but MC will divorce her because he finally gotten some balls and will propose to her once again with good rings and etc.)
Anyway, I'm a dumbass who knows that reading Josei is like inflicting pain to oneself BUT i had found some gems among this shit that makes me mad and because of that i sometimes indulge in this demoralising genre in order to once again find gems
MY PERSONAL RECOMMENDATION : Hokuo Kizoku to Moukinzuma no Yukiguni Karigurashi
FMC is a strong warrior noble woman who has problems finding a mate due to her exploits, MC is a norther noble who lives in a very harsh and remote location, quite handsome(beautiful?) and feminine. During their life together they change and become partners complimenting each other. FMC becomes more feminine and MC becomes or reveals his masculinity (C'mon living in harsh conditions) It's a more Slice of life, sweet story of a wonderful family WITHOUT CHEAP DRAMA (Meaning no freaking triangles, NTR or ther BS)
