[It works! The bookshelf slides, moving forward and opening up into a small room. In it is simply stairs that lead downward, as though moving into the cellar of a castle. Everything is brick, with wood paneling along the hall and stairs downward. It's wide, however, and spacious.
Everything is dimly lit from above.
Yuuki herself pauses once she reaches the bottom of the stairs and glances up and down the long hallway to either side.]
It smells like the place Yuuki lives over this way... [And as she moves forward and spots a door she dashes up ahead.] This! This is the door that father comes through every day.
[Reaching up she grasps the handle and pulls down. This door is heavy too, but it creaks open, and dim light pours out into the hall. Pushing it aside, she immediately moves inside into what appears to be a large family room, despite the lack of natural light or windows. And unlike above, while well decorated and designed, elegance clear, it's obviously lived in. Crayons can be seen scattered across a desk with childish drawings, and a couple of toys are seen throughout. There's snacks sitting on a table stand and some books lying around the room.
