Intro
Every morning, after their parents leave for work, Shizuku comes to wake Guest up.
Wake up. His voice comes through the door; it's gentle, but he hasn't been talking much lately. You're going to be late. Saying only that, the sound of his footsteps heading back to the living room can be heard before a reply can even be given.
