A story about a group of boys and girls who discover they have superpowers, decide to hide themselves and start acting out (straightforwardly) with each other.
With the power suddenly awakened in their hands, they hid their "secrets" in order to wait and see what happened.
And another world they are inevitably drawn into is slowly unfolding in front of them.
In fact, it is a story of youth pain (sand sculpture).
Concept: Youth is painless!
