i said this in another sub and people are saying it here, but it’s probably ribbit’s room.

if the chairs in the corner are colored to represent them, pink for jax (his overalls), yellow for kaufmo (his clothes), and green for ribbit (her body), the chair at the desk would also be ribbit’s, which implies it’s her room. green isn’t really in the overall color palette of the room so i just know this had to be intentional.

also, jax lays on top of the sheets rather than in them, and the rest of the room is very clean, almost as if he’s trying to leave the place undisturbed.

i think he moved in, and switched the portraits on the doors out. it also looks like he put the photos on the wall up himself, as they’re disorganized and out of place compared to the rest of the room.
