In the small town of Lumina, there were two children, Mia and Leo, who were known as the "Invisible Pair." They didn't have much—no fancy toys or brand-new shoes—but they had an unbreakable bond and a secret garden they had built from things others had thrown away.

Mia and Leo didn't hesitate. They ran into the rain, using their knowledge of the "junk" they collected to build a small trench system. They used old wooden planks and stones to divert the water away from the playground.
