Saengsu was an ordinary child who loved to draw. After her parents' business failure and suicide, Saengsu was traumatized, resulting in diminished intelligence. Now, she precariously sustains her life with the thousand-won bills she receives for running errands for high school students' cigarettes. Her grandmother, her only guardian, was taken to a nursing home for boiling a neighbor's pet dog with the sole intention of helping Saengsu. Saengsu's only way to bring her grandmother back is to pay Kkamssi, who sells colored chicks in front of an elementary school, one million won to take over his spot. With that single hope, Saengsu runs with all her might every day, buying Marlboros as ordered by Cheol-gwon, a fearsome figure who wields chopsticks sharpened like knives. Eun-yeong, Cheol-gwon's girlfriend who makes Saengsu run errands for Esse, is like an angel to Saengsu. Seeing her brings a smile to Saengsu's face. Eun-yeong is a kind person who gives her more than just a thousand won, offering extra change to buy pencils for drawing. One day, when Saengsu was detained by a detective's misunderstanding while struggling to deliver Esse to Eun-yeong, that day was the day the thousand-won bills became 1000 times, the day she completed one million won. Saengsu, returning Esse to Eun-yeong and running to her rooftop room in jubilation with the last thousand won. However, the money was gone, and beneath the drawing Saengsu was working on, a Marlboro cigarette butt was discovered.
