This is a story of a girl who has a shadow that always wants to hang around. The shadow never wants to cause any trouble for the girl, but somehow seems to always want to be by the girl's side. After the girl takes a break from trying to get the shadow away from her, she lovingly realizes that the shadow is her little brother. The girl finds out that the little brother wants to do everything that she does because he looks up to his older sister. She then welcomes her shadow "little brother" to follow her wherever she might go.
If you happen to be an older sibling, then you might know how a shadow clings to your side and copies your every move. Now if you have a shadow, a little sister, or a little brother that might be hanging around you too much, just try to show them how to have a good time!
