Seventeen-year-old Zhou Suihuan met a boy.
But one day, everything about him disappeared.
An accident occurred when she was twenty-one. She lost all her memories and returned to the spring when she was sixteen.

The two people, who were both regarded as aliens, had a false dream in that world.
Intention: Destiny cannot be reversed, but the encounter itself has weight.
