Kokichi and Shuichi are in the kindergarten. They are best friends, so they always spend time drawing, playing, and sleep together when it's nap time. The caretakers planned a sleepover for the kids, so they had to choose someone to sleep with.

It was finally the day of the sleepover. Shuichi walks towards Kokichi, both already wearing their pajamas, while holding his blanket with his tiny arms.

"H-Hey, Kichi! Let's go sleep t-together!"
