Xu Qing thought she had stable happiness: Chen Mo, her boyfriend of eight years, had a successful career and the two were about to get married. Even the wedding room was chosen on a high floor with a view of the river. Until she ended her business trip early and wanted to give Chen Mo a surprise, but in that house full of their longing for the future, she broke the intimacy between him and her best friend Lin Weiwei. The eight-year relationship became a joke, and the betrayal of her best friend was like a poisoned knife, splitting her life into pieces. In the days that followed, she struggled in the ruins, but got entangled with Jiang Yu, a man who also had scars - he was Chen Mo's business rival and the only person who had seen her in the most embarrassing state. Misunderstandings piled upon misunderstandings, betrayals followed by calculations, Xu Qing was repeatedly pulled on the edge of love and hate. She thought she was seeking redemption, but she didn't know that everyone was trapped in their own obsessions, and even the last tenderness was scorching and stinging.
