He leads the way to the kidnapping room specifically. He may not need to steal him and hide him away, but he likes having this room just for Persephone. Hidden away, where no one will pry, and with a view, too.

The koto awaits him there, as well as a bonsai tree, and any supplies you might need to care for it.]

Here. Play something, would you?
