Looking for a enemies AND lovers romance book

To put it simply I just want a romance book that the FMC hates the MMC(s) but he ABSOLUTELY LOVES HER. I would prefer (but not needed) if the FMC is the villain or morally gray hero. OR if the MMC and FMC are on different sides but fall in love

Would like a FM story but it's fine if there's a bit of MM or MMF

I'm fine with reverse harems but not needed

Low-angst preferably

It doesn't need lots of smut just a lot of fluff
