In a land, where there isn't one Sandman but many, they are unseen to us and are the ones who put everyone to sleep and grant good dreams.

There is a new Sandman called Leo, he is young and quiet. His job is to make sure the children of Seoul fall asleep and have sweet dreams.

However, he is lonely... the older Sandmen are stern and look down apon him.

Because of this Leo sinks more and more into himself and starts messing up on the job. He isolates himself and becomes sad. 

Then one night on a normal job, he is so distracted and by mistake is seen by a child.

All he sees is a big smile, smile eyes and he is whirled away into a world he is not used to with a simple invitation.

"Do you want to play with me?"
