I have a vague memory of a scene and I want to know what it's from. I can't say if this is from a book/movie/show, or even if it belongs in this stack exchange category, but let me explain it as well as I can and maybe someone here will know what I'm talking about.
What I remember is this: There was a character who I believe was female, and I believe she was being held hostage(?) by a male character, who was the antagonist. I believe the male character was interested in her romantically, and she (as the "good guy") was obviously repulsed by him and avoiding his advances.
But she needs to get something from him, in order to escape, perhaps? Maybe keys, or a weapon? Something he has on his person. So she pretends that she's interested in him, and tricks him into kissing her and while they're kissing she attempts to grab this thing from him, but just before she succeeds, he realizes what she's doing and backs away. And he's very upset to realize she wasn't being sincere and was just trying to escape.
I probably have some details wrong, but hopefully someone can figure out what I'm talking about!
Quick note: There's a similar situation to this in the book Shatter Me. The scene from that book is what triggered the memory, but that's not the answer.
Edit: I think it was probably a scene from 3x18 of Once Upon a Time, although in that case I had the genders wrong. I was also imagining something from longer ago in my past, whereas I would've watched this only three or four years ago. But this is the most likely answer. Thank you to commenters for helping!
