Playhouse would take place simultaneously with events of the main story and be primarily from the perspective of Dave focusing on how his life goes from here:

to here:

(and maybe a few scenes further back in time to when he and Caleb first met/before Caleb was traumatized)

Dave's main unhealthy coping methods are avoidance and denial, so the story would delve into what happens when these strategies cease to work for him and how he goes from a seemingly well adjusted individual to an alcoholic mess.

Much like how the main story focuses on Caleb and Bunny's toxic relationship, the plot of Playhouse would focus on Dave attempting to sort out his sexuality and obsession with Caleb through a complicated situationship with a new character, Jay.

Jay has his own host issues, and Dave makes it his mission to "fix" him primarily so he can figure out how to "fix" Caleb, which is a great foundation for a relationship.

Some chapters would also be from Bunny's perspective delving into her past. You'd see more of her "boyfriend" before Caleb and what really happened to him at Lover's Leap, as well as Bunny's stay at the mental hospital.
