Imagine your otp broke up years ago and haven't seen each other since but still had feelings for each other, and one day person B, at a bar or somewhere, sees someone and decides to give it a try and goes over to flirt, when the person turns around to see who's talking to them, it turns out to be person A and when they both realize person B was trying to flirt with person A again, things get really awkward
