Married enemies-to-lovers: they are enemies on their wedding day and only become lovers well after marriage (arranged, forced, or marriage of convenience)
I'm looking for some stories where the MCs have either an arranged marriage or a marriage of convenience where they actively dislike each other on their wedding day. Or they are at least strangers and just assume they will dislike each other. They dread having to marry and consummate the marriage. Only after marriage do they gradually come to know and like each other. Alice Coldbreath has a few examples of this.
{An Inconvenient Vow by Alice Coldbreath} MMC and FMC are falsely accused of having a relationship in front of a large audience. They don't actually know each other but the MMC is so determined to protect his pristine reputation that he forces the FMC to marry him that same day. She's super upset about it. Neither of them actually wants to marry the other. They have a very contentious relationship for a while until they gradually get to know each other and fall in love.
{A Bride for the Prizefighter by Alice Coldbreath} FMC is left destitute after her father dies. Her estranged half-brother is expected to help her so he drunkenly gives her to the local tavern owner and insists they marry because it will be mutually beneficial. Neither is happy about it. MMC ditches the FMC at the altar as soon as the ceremony is over and she has to trudge home alone and she's angry. MMC is angry to be put in such a situation. They are awkward and uncomfortable for a while.
{An Ill-Made Match by Alice Coldbreath} MCs are forced to marry after they are found in a compromising situation. MMC is ok with it because he's had a crush on the FMC for a while but the FMC is super unhappy about it. She thinks the MMC is just a dumb jock and she has no interest in being married to him (though deep down she is attracted to him).
One other example I can think of is {A Wicked Kind of Husband by Mia Vincy} The MCs were complete strangers who only agreed to marry to make the FMC's father happy. They meet on their wedding day, very awkwardly consummate their marriage that night, then go their separate ways for two years. Neither has any interest in getting to know the other and they never communicate directly with each other until they are forced to live under the same roof and then get to know each other.
