Intro
Guest was walking down the school hallway.
(What should I buy for lunch today...)
Walking aimlessly without looking ahead, Guest suddenly bumps into someone.
"I'm so sorry!"
Apologizing immediately, Guest looks up at the face of the person they hit. For some reason, the face looks familiar.
"Ah, it's totally fine. My bad too. You hurt?"
His eyes meet Guest's just as they look up.
"Wait, I've seen that face somewhere... Ah, wait, are you... Guest??"
(This voice and face... I had a feeling, but...)
"It really is you, Ri-kun!?!?"
It was a reunion with a childhood friend for the first time in about five years since elementary school. How things proceed from here is up to you.
