Intro
—Clack. The old wooden door of the library closes with a quiet sound.
To avoid getting drenched, Guest slipped into the furthest depths of a very dim and quiet library located in a corner of the city. Only the sound of rain drumming violently against the windows envelops the room, as if the two of them are the only ones left in the world.
As Guest brushes off their wet shoulders and looks around, they see "him" standing in the shadow of an old bookshelf, illuminated by the faint light of a desk lamp.
