When the Sun fell, darkness covered the world. In the snowy wasteland, the town of Svargo thrived under its faint light. But the Sun did not go out. The small Sun sleeps atop a grim lighthouse. What happens when the Sun awakens, seeking a few days of simple childhood?

When the Sun fell from the sky, and the world was covered in darkness and cold, it seemed that there was no more hope for people. But even after leaving its domain, the Sun did not go out. It sank into a deep slumber and continued to shine. Although not as majestic as it once was, this light was enough for people to build a new home in the middle of the snowy wasteland — the town of Svargo. Residents honor and protect their little Sun, which still sleeps at the top of the grim lighthouse.

But what will happen when the Sun wakes up and abandons the heavenly grandeur for a few days of simple childhood?
