Lin Xiaoyu and her college best friend Wang Manya are like sisters. Wang Manya moved into Lin Xiaoyu's house when she was in trouble, and the threesome pattern quietly penetrated. After the success of starting a business, Lin Xiaoyu divorced twice. Wang Manya enthusiastically took her in each time, but in fact she was planning it secretly. She first invested in the company to obtain shares, and then gradually took over the finance and operations, marginalizing Lin Xiaoyu. Chen Hao wavered between the two women, and in the end Wang Manya used her scheming to seize the company, family property and Chen Hao. Lin Xiaoyu had nothing, raised her children alone, and watched her former best friend get married to her husband. Twenty years of trust have gone up in smoke, and the deepest betrayal comes from the people closest to you, and it's infuriating.
