Pioky and Four are friends since kindergarten, when they were six years old. They care a lot for each other, and have fun together. Pioky is more the calm, sweet little boy, while Four tends to be more active. But that one time during their day in kindergarten, after a lot of running and playing around, they both are pretty tired, like the other kids. So when their teachers decided its time for getting some rest, Pioky always cuddles himself against his best friend, who protectively holds him, making him feel safe.
