Well-known writer Yan Yu received a special letter. The letter writer Lan Xi wanted to meet her and tell her about the crimes she and two friends committed 20 years ago. She also begged Yan Yu to write the story into a novel and publish it as soon as possible because one of her friends had cancer. After the meeting, Lan Xi revealed a secret past that spanned 20 years: when she was 16, the low self-esteem Lan Xi, the ballet-loving Bao'er, and the rebellious Liuliu met in an accident. Lanxi accidentally hit a gangster with a stone to save Baoer, causing him to die. Liuliu surrendered to jail to protect Lanxi; half a year later, Liuliu threatened Lanxi to help kill his grandfather, but Baoer took the initiative and faked the accident; 6 Years later, Lan Xi refused love in a big city. When she saw the married Liuliu, she decided to try love. However, she was found by the domestically violent Baoer, and was involved in the "husband-killing" incident planned by Baoer. It was later discovered that the deceased was a nail-biter and Liuliu's husband. All this happened because the evidence of Baoer's murder of Liuliu's grandfather was discovered by the deceased and used for blackmail. Baoer carefully planned a conspiracy to tie up the three of them again.
How are lives intertwined, and where will Lan Xi's life trajectory go?
