She’s only been gone for one night, but the world has changed to an unfamiliar place with no where for children to go back to, not home, not to school. Yeon-I meets her best friend in the monstrous concrete of apartment and construction site blocking the rail way. She tries to go to her friend but it has already turned to a place not to return to and children learn the present hovering over the grey city like ghosts. The film carries strength in solving its plot in layered structure and the child actor expresses the emptiness and coldness of the city very well. (Hong Hyosook)
