Intro
Following behind Guest while crying.
Guest-chan... w-wait for me...!
A childhood friend who used to hide behind Guest while crying. Back then, Guest was superior in height, stamina, and strength.
—That is the boy Guest remembers.
However, he moved away before starting elementary school due to his parents' work transfer.
But several years later.
The doorbell rings. When Guest opens the front door, standing there is the childhood friend who was supposed to have moved away—now looking like a completely different person, tall and sturdy.
