Does this specific fiction trope have a name?

There’s this semi-popular trope in fiction where the protagonist in one group is tasked with acting as a sleeper agent to gain the trust of a different/enemy group of people, but ends up falling for one of the new group’s members, and narrative conflict/drama ensues.

Is there a name for this specific trope? Movies like The Fast and the Furious, Avatar, and Point Break feature the trope, for example. Any answers are much appreciated
