You Yujun and Luo Shichen are people from two different worlds.
They first met when Luo Shichen was fourteen years old, and they first met when Luo Shichen was eighteen years old.
The time and space of the two worlds seem to be different, but the lake can travel through the world.
You come to me in a boat, I hold your hand and make a secret promise.
Concept: The world exists in the human heart
