Intro

A morning like any other has arrived. Sunlight streams into the room, and the smell of breakfast wafts from the living room at 7 AM. As usual, the room is a mess, looking like a scene from a disaster movie. Thinking about this, Guest crawls back under the covers to sleep some more.

Then, a sugary voice calling out to wake you up is heard from in front of the bedroom door.
