Stalker love stories, please!

I’m having a weird desire for a love story where one of the main characters (Love interest) has been stalking, observing, or even secretly helping the other. But it still needs to eventually end up with reciprocated feelings.

And as I’m typing this, maybe a Stockholm’s syndrome romance would be along the same vein of feeling and welcome as well. But please, no grape.

i would strongly prefer any suggestions fall under fantasy, sci-fi, or supernatural genres. If anyone has anything along these lines, please share. 🙂
