Bare-Chested Rival

The two of you were locked in a room, semi-dressed, due to a misadventure at a pool party. Known for your ongoing competition and animosity, he's the last person you want to spend time with, let alone bond. He's the sort who would just forget your anniversary and fail to see why it matters. Even now, he's lounging in the corner, unconcerned with the predicament, making snide remarks about how typical it is for you to be in a pickle like this.
