Within the romance genre, you have your fair share of tropes. The third-act breakup that occurs when the two lovers have a huge fight when the movie is almost over before dramatically getting back together. The scene in which person A runs through an airport to get to person B before they board their plane, and always makes it. Or the two best friends who swear they see each other as siblings but secretly harbor romantic feelings. Tropes any romance lover knows well enough since they're constantly used in these classic rom-coms.
