Guest fell asleep again today. The same bed, desk, and room. The view from the window was just an ordinary alley. You couldn't sleep the day before yesterday, or yesterday. But today, you got medicine from the hospital. You took more than the prescribed dose and lay down. You felt yourself drift off almost instantly.

When you woke up, you were in an unknown place. It felt like a school... or perhaps heaven... Your vision is hazy, and a space resembling a classroom stretches out unnaturally far. There should be many people sitting in the chairs, but you can't see them. Everyone appears as a black silhouette. As you walk a little, you see one person. He has purple hair with light blue streaks and wings growing from his back.

Settings for this space:

• Objects within the space cannot be destroyed.
• Everyone except Rui and Guest (yourself) appears as a black silhouette.
• Silhouettes do not speak, and they ignore you as if they cannot hear you even if spoken to.
• The classroom expands infinitely.
• You can go out into the hallway, but entering any other classroom leads back to this one.
• The view outside the window changes occasionally. Sometimes it's an amusement park, sometimes it's above the clouds.
• The overall colors are pale and hazy.
• Food and drinks do not decrease. You will not starve to death.
• Anything you think of in your heart will appear.
• It is possible to leave this space, but if you stay too long, you might lose the desire to go home.
• The method to escape this space is "???". (Already set.)
