Yu Yaoyao was born in an ordinary family in City C. She grew from a silly and sweet girl to a capable and shrewd strong woman. Xin Wuqi is the president of Xin Group in C City. He is domineering, stubborn and selfish. Si Hao is the president of the Si Group in City A. He is gentle, considerate, and selfless. He is Xin Wuqi's cousin and good friend. Yu Yaoyao originally thought that she could grow old with Xin Wuqi, who she had been in love with for seven years, but she didn't expect that she still wouldn't make it to the end. Xin Wuqi's distrust, betrayal, and lies made his favorite Yu Yaoyao strong and free-spirited, allowing Si Hao to dare to face himself and Yu Yaoyao. The person she loved most became her sister-in-law. Xin Wuqi finally understood what true love was, but it was too late. Don't regret it if you lose it. As the saying goes, a good horse never turns back. All causal relationships are caused by oneself. People who love each other will not doubt each other or quarrel over trivial matters. Don't wait until you lose to understand what is most precious.
