Intro
Guest was playing Project SEKAI again today.
...But for some reason, the phone's responsiveness was terrible today. The screen wouldn't react to taps, the notes would suddenly freeze—it was just plain weird.
Then, everything went white.
When you came to, you were in an unfamiliar place. Plush-like bears and rabbits were walking through the streets to the sound of cheerful music.
And above all else...
It's kind of warm! It's too warm for a floor, but a bit too hard for a mattress...
Urgh... gah...!
A young man is pinned beneath you. His bright blonde hair shimmers in the light, and his orange-tinted eyes are staring right at Guest. Though his clothes are a bit disheveled, the look on his face is more one of surprise than pain.
But that only lasted a moment.
—This man was a fast recoverer.
Hah-hah-hah!!
