https://yaoimangaonline.com/jinx-by-mingwa-eng/109/ it's a bit full of adds but here
bl manga where the uke is an ex host or playboy or womanizer or all three... i cant rlly remember much abt the seme but he locks the uke up in his house or smth.. uke was i think blonde, seme black hair. sorry for vague description
this manhwa fits your description so much but instead it's the other way around, the blonde is the seme and black hair is the uke...
