TV show that builds up like the main character is having an affair, all lingering camera shots of stuff her side piece left on the floor at her house, only for it to turn out after six or seven episodes of tension that they were polyamorous all along
TV show that builds up like the main character is having multiple affairs with different people, often in some kind of inappropriate context, only for it to turn out after six or seven episodes of tension that her partner is a master of disguise and they're engaged in increasingly implausible roleplay scenarios.
The reveal for this is that the camera pans from them having sex on the bed to the half-open closet and it's just like, full of different wigs and uniforms, only some of which have appeared in previous episodes
TV show that builds up like the main character is having multiple affairs with different people but it's never shown in person, only the main character having conversations with different people when their partner isn't in the room on text and calls and meetings with these people are just shown as the person arriving but never fully shown - only for it to turn out after six or seven episodes of tension that their partner is a DID system and the main character is just dating all the members of the system and they all support this.
The reveal for this is just the main character and who we think is the partner we've seen the first half of the show sitting on the couch, but main character calls them by the name of another partner, and we slowly see the main character go on dates with all of their partners and then get to see how the dynamic is different with each alter in the system.
Edit: Also there's an aroace alter in the system who is revealed to be the friend the main character has been talking to for dating advice the whole time. That alter finds this whole thing very cute even if dating isn't for them.
