The singer and the person she's singing to have already hooked up, while the singer was in a relationship. The subject didn't realize the singer had feelings for the subject (possibly due to the preexisting relationship). I feel like they knew each other beyond their hookup, and she sees the subject as inwardly complicated, despite their projected confidence, and feels like she knows them in ways the social crowd doesn't see.
