cold mmc that doesn’t stop being cold after getting with the fmc

does the title make sense? i truly hope so!! times like this are the only time i ever wished english was my first language.

i really really love a cold hero. they’re usually cocky/arrogant, straight-forward with their words and when that is done right it makes me feral. i really really hate when they turn into a golden retriever once they get together with the fmc - even if it is only in private. i want an mmc who remains cold cause that’s who he is but that doesn’t mean he ain’t obsessed with his woman. fmc accepts that - is even charmed by it.

so to sum up, i’m looking for your cold(est) mmc recommendations.

bonus: slow(ish) burn, tension, foreplay, enemies to lovers

no: romcoms, big age gaps (12+ years), teenagers, noncon

thank you!!
