I think I imagined it

Can anyone help me find a movie I saw in a edit a year ago( it was deleted before I could save it😢) It’s where I’m pretty sure they’re is a side character that’s a black lady and she had this like 70s style with big hair and she was in love with a white guy I’m pretty sure his hair was like blonde/strawberry blonde and he wore black and was always smirking. They both were real lovey dovey. The movie gave vampire vibes but I’m not sure if it’s a vampire movie.
