The second season of "Bridgerton" is all about the maddeningly intense attraction between Anthony and Kate. Despite their mutual loathing turned lusting, Anthony still tries to go through with his promise to marry Edwina, only for the wedding to be called off when his real feelings become clear. Left alone in the abandoned chapel, Anthony and Kate bid each other a heartbroken farewell, but not before sharing a searing and passionate first (and, they then believe, their only) kiss.
