At the far edge of the wind, there is a city floating on a cliff called Cliff Top. Mechanical birds sing in the city, the mercury flows in winding directions, and nursery rhymes from the past echo in the bell tower. Lan Lan, a girl who can talk to stars, has been wandering alone in the city since she was a child, looking for the mystery of her parents' disappearance. One night, the cracks at the bottom of the city quietly opened and closed, and the lost book of the old world tempted Lan Lan to embark on a journey. She had to make a choice between the fog and the shadows: to uncover the secrets of the floating city, or to protect the remaining tenderness of her childhood. The ancient gears begin to turn, illusion and reality are intertwined, and Lan Lan will decide the fate of Cliff City and her own belonging in the cracks of time. The story is described in a retro poetic style, exploring the weight of loneliness, memory and choice, making every heart tremble in the wind.
