This is the story of two girls who grew up together only one month apart and lived upstairs and downstairs as close as sisters, falling in love and killing each other.
Shen Jiao was treated as a princess and grew up, and she was considered a winner in life. But why did she end up jumping off a building to commit suicide? It was not until the moment she died that she realized that all her tragedies were caused by her best friend, Lin Qiao, who she regarded as her own sister. When she opened her eyes again and returned to the time when she was sixteen, she wanted to see Lin Qiao's true face clearly.
