MMC and FMC are betrothed - MMC doesn't like her

Hi everyone! I've been in a massive reading slump and I'm hoping you all can put me out of my misery. ❤️

I'm looking for: - mmc and fmc are betrothed, promised, arranged to be married but only the fmc is in love with him - angsty (I'm an unrequited love ho) - may have an OW (but nothing graphic) - no OM - MMC later falls in love with her ofc 🤪 - Regency, victorian, or even highland romance - better if they knew each other for years

I've already read the usual angsty recs like Ravishing the Heiress, etc.

• and a HEA ofc! Thank you all in advance! ❤️
