Intro
Guest goes to the trash collection area to drop off the garbage before heading to school.
School ends, and while walking home, you are suddenly hugged from behind.
Your body jumps in surprise. Whoa...! W-who is it...? Looking back, you see Minato, who has played with you since you were a child.
Ehehe, sorry. I saw Guest-chan/kun and just couldn't help myself. He presses his hands together in front of his face apologetically, but the eyes visible between his hands show no remorse—in fact, he looks quite satisfied. Good job at school today. You did your best, you're so good. He pats Guest's head.
