Ani becomes known as "The Saintess of Rebellion" as her last conversation with Bernadetta (this is AFTER she finally stands up for herself and SEIZES her future, by the way she becomes Prime Minister, the FIRST Female one AND becomes her Sperm Donor's Heir, don't know her brother's fate though) and decides to make "meaningful changes" within the Church! That is "going Martin Luther on their asses" LOL! Hence the name change. One of those is "choosing her own fate and Lover" with the man she chooses being a Dark Mage! They have a daughter who inherits her father's Dark Magic! Not much is described of her Husband! But knowing Ani's past and her now being "more careful around men" meaning she ISN'T going to go for guys similar to her "two former simps" but I think seeing how the Future Queen and King's daughter is her daughter's best friend! I assume she has no hard feelings towards the two, especially Erik, so a Man like him, only NOT engaged or promised to someone else as she DEFINANTELY LEARNED HER LESSON IN THAT REGARD LOL!
But yeah the Epilogue follows Sera and Erik's daughter (I believe the younger one as they have four kids I believe, and OLDER Daughter and Son, and another son younger then the daughter mentioned) going through her OWN "condemnation" by her now EX fiancee, a Duke's son abandoning her ARROGANTLY for a Baron's daughter! She doesn't fight it and Ani's daughter, who was watching, mocks the idiot, Sera's daughter not caring much for the idiot and more annoyed she has to FIND ANOTHER FIANCEE since as they make clear talking with each other, the fact the Ex STUPIDLY slighted THE FUCKING PRINCESS for a Baron's daughter! The most likely outcome when reality hits the smug fool is he'll be disowned and knock down to commoner! I think a joke is made if his "mistress" will still want anything to do with him once it's clear she "didn't outperform a Princess and rise into a Duchess, and wasted her time on a Dud" as it's noted he has brothers! A second and third one, meaning the likely outcome is the second will become heir and third will become the spare, while he'll get WORSE as the Third is usually given ADVANTAGES before they get knocked down to commoner to be a FUTURE ASSET to the family later on if they do make something of themselves! The fool won't even get THAT! Wonder how smug he'll be when his "precious TRUE LOVE" abandons him!
This is also where they talk about the "Rumors" that Sera and Erik might "get a divorce" and things aren't so good in the marriage! Which neither believe, ESPECIALLY the two's daughter who brings up the fact they keep their love PRIVATE that only their children know! Finding it STUPID those "Rumors" still have ANY steam in them despite the OBVIOUS fact THEY HAD FOUR KIDS NOW! Even under OBLIGATION, no couple that HATE each other would go over ONE if the first was a Boy, yet they had FOUR KIDS! As said in my other comment/spoiler! The two don't OUTWARDLY show their love, so idiots keep THEORIZING because of that that they don't love each other. They keep that to themselves! It started as respect, making the engagement work out because they weren't RESENTING EACH OTHER A SABOTAGING IT OUT OF STUPID SPITE! You notice that in ALOT of OTOME! The Manga about the Villainess having 24 hours to avoid her bad end is a perfect example as it's made clear the Prince is largely trying to ruin her out of SPITE AND RESENTMENT instead of being smart and quiet about it! FMC was nice enough to POINT THAT OUT TO HIM AFTER HE SCREWED HIMSELF! Alot of these Otome always have the Prince "STBX" always act in RESENTMENT to his "lack of choice" so THAT is why ERIK is the rare REFRESHING subversion, where he's ALOT like the "Second Prince's who exist to replace those losers when they inevitable get DISINHERITED for their PURSUIT of "freedom over duty" (Turns out their Wishy washy assholes in the end, they WANT freedom, but they WANT the power their DUTY gives them at the same time! Cake Eaters "get NEITHER" LOL) and he and Seraphina DO fall in love eventually PAST their "Duty" during their marriage BECAUSE they don't RESENT each other! That's a nice observation from the writer that SOME Arranged marriages CAN work out if the two are compatible already AND learn to communicate instead of FIGHTING each other because of resentment better DIRECTED at the MORE DESERVING their too CHICKEN SHIT to do so at, THEIR PARENTS!
