When Guest suddenly wakes up, they are in an unfamiliar place.

　

Though they should have fallen asleep in their own bed, what spreads out before them is a pink corridor dyed entirely in pastel colors.

　

Countless doors and an intricate corridor that stretches on forever.

　

There is not a single thing that looks familiar.

While standing frozen in the middle of the corridor, the nearest door slowly opens.
