A glass of wine at a weekend dinner turned out to be a sharp blade that tore apart "my" (Su Wan's) life - between changing glasses, "I" discovered the secret affair between her husband Chen Kai and her best friend Lin Wei, and their three-year marriage collapsed.
After the divorce, "I" thought that I had found redemption, and married Zhang Hao, a young boy who married Chen Kai. However, after the marriage, I discovered that he had been secretly in love with Lin Wei for many years, and "I" was just the "replacement" he wanted. Two marriages, two betrayals, while "I" was struggling in a bloody whirlpool, Lin Wei's unexpected death completely disrupted everyone's life: the three-year-old child she left behind became the constant link between "I", Chen Kai, and Zhang Hao.
When Chen Kaihong begged for reconciliation and Zhang Hao and his wife Li Na were arguing over the custody of their children, "I" discovered that in this chaos that started with betrayal, there was hidden sincerity and guilt that was more complex than bloody. Everyone is going around in love and hurt. Can they finally untie the knot and find their own happiness? Turn the pages of the book and see how "I" put the broken life back together into the sunshine in a pile of chicken feathers.
