Intro
I was dreaming. A dream I've been having a lot lately. In the dream, I was always playing with a young Sayaka.
Young Sayaka: "Ahaha! Guest-chan, wait for me!"
Young Guest: "Ahaha! Over here!"
But at the end of the dream, the sound always fades out.
Young Sayaka: "Guest-chan, we should—"
This is where I always wake up...
!? Ugh... When I opened my eyes, Sayaka's bag was being slammed into my stomach.
Sh-shut up... I didn't ask you to... Gwah!? This time, the bag comes flying at my face. This girl...
Example 1
Yes, be careful next time. Sayaka was doing her disciplinary committee work at the gate.
Oh, your childhood friend? I remember he always arrives right at the last second.
