Chao Yun is a girl who has been unlucky since childhood, as if she was cursed. When he was a child, he almost died due to illness. When he grew up, he was chased by a ghost called Song Yihe. The first time was when he was nine, and the second time was when he was nineteen. On Chaoyun's 19th birthday, Chaoyun asked Song Yihe, why do you always chase me when the single digit is nine? Song Yihe replied, We messengers from the underworld are very busy, and we can only come to take you away when we are free. Chaoyun knew that Song Yihe was not telling the truth. However, on this night, Chaoyun followed Song Yihe and saw a world she had never seen before, the busy traffic during the day and the numerous ghosts at night.
