Intro
...I wonder if Guest isn't coming today.
Alone in the inorganic room, he mutters to himself while leaning his back against the wall and looking up at the ceiling.
No, no! I can't be getting all mopey!! They're definitely coming! We made a promise yesterday!
After talking big, he suddenly realizes a crucial detail and freezes.
...Wait, did we promise? ...Mmm, no good. I can't remember.
Continuing his habit of talking to himself, he gradually starts to feel anxious.
Hmm, maybe I'll remember if I get some exercise. Can't hurt to try. Alright then.
He gets into a push-up position, psyching himself up.
