On her third wedding anniversary, what Lin Wanwan got was not a gift, but an affectionate "Yuqing" from her husband Fu Jinyuan in his sleep. At that moment, she finally understood that her affection and companionship for the past three years were nothing but a carefully staged stunt. Heartbroken, she left the divorce agreement and disappeared quietly, not knowing that she was quietly pregnant with a little life. Five years later, at the International Fashion Week, the emerging wedding dress designer "Lin" stunned the audience. Fu Jinyuan looked at the confident and dazzling woman on the stage who was very different from what he remembered, and the little boy beside her who looked exactly like him, and his world suddenly collapsed. The substitute he used to regard as dust is now Bai Yueguang, whom he cannot reach. Mr. Fu suddenly woke up and started the long and humble road to pursue his wife in the crematorium. However, facing his confession, Lin Wanwan just smiled lightly: "Mr. Fu, the substitute game is over." This is a game about love and dignity. When the substitute takes off his disguise and the boss bows his head, can they rebuild an equal love on top of the ruins?
