The Protagonist's house is one of multiple locations in Adventure High.
The Protagonist lives here with an unseen mother and a briefly mentioned father.
The house has three known rooms: a kitchen, which you can leave an inanimate Brittany in, a living room which you can leave an inanimate Jane and Eric in, as well as the Protagonist's bedroom, where most of the play with scenes takes place.
You can also leave an inanimate Ms. Rack, Sarah as a doll and Victoria in here.
Little is known about the house but Val seems to hang out there in the afternoons. It's unknown if she does so because she's a slave or she just likes to hang with the Protagonist, though knowing her personality, it could easily be both.
Known visitors
The following people are known to have visited the Protagonist's house at least once without being enslaved (or, in Derrick's and Veronica's cases, to become a slave).
Val, who hangs out there in the afternoons.
Sarah, who shows up there if the Protagonist is dating her or she comes with the Protagonist to be turned into a doll.
Julia, who comes there if the Protagonist is dating her and has fixed Ashley's mind.
Cassandra, who presumably starts living there on the Submissive route.
Ashley, who moves into the Protagonist's house - and seemingly sleeps on the couch - after her mind is fixed.
Molly, if the Protagonist is dating her. Seeing Jane, Ms. Rack or Sarah in their inanimate forms, however, causes her to quickly question what she's gotten herself into. If Val is in her bimbo form, Molly will quickly leave the house without another word.
Ms. Rack, who shows up if you have not enslaved her but started the lover route with her.
Erin, who shows up if the Protagonist told her that s/he was going to tame her at some point.
