These are completed~
It's moreso the guy thinking the girl is his rival/enemy and then falling for her. It's slow paced and starts when they're kids https://www.mangago.zone/read-manga/last_game/
Hated princess gets sold off to the enemy country as a bride for the enemy prince. They hate each other at the beginning. It's mid-paced (not super slow). https://www.mangago.zone/read-manga/reimei_no_arcana/
They fall in love pretty quickly but they don't know they're each other's enemy:

Omg I was recommended basara so many times but I couldn’t get into it ! Thank you so much for the recommendations
Basara's one of my all time faves but I get it. Honestly the art and story-telling are pretty old school plus it doesn't have doki doki shoujo vibes. I like political, historical (though Basara is actually futuristic), and war manga so maybe that's what did it for me.
Ok but omg i binged read 90s cram school for unriped apples and it was literally the best slow burn I ever read of my life so far THANK YOU
