Yun Chuyue, who had the same name but had always been a koi carp since she was a child, was unlucky one day. She stepped on a manhole cover when she went out and died. When she woke up, she became the hard-working and unlucky Yun Chuyue of Luoshui Village.
Yun Chuyue lost her mother to death when she was ten, her father to death when she was fifteen, and her brother to death when she was sixteen. The eldest brother of the Yun family felt that he could no longer keep her, otherwise he might destroy their family one day, so he married her to a fool.
Facing the idiot husband, the stepmother separated and had nothing, Yun Chuyue felt that with her koi physique, she should be able to save her.
