Cai Meng, a young and beautiful actress from the Qinqiang Opera Troupe, is the girlfriend of the Qinqiang director Ideal. The two struggled to raise funds for a Qinqiang opera. When Ideal was determined to propose to his girlfriend, his ex-wife, Han Qing, a former actress from the troupe, unexpectedly returned from another place with a five or six-year-old boy named Dazhi. Because half of the property rights of Ideal's house belonged to his ex-wife Han Qing, the current wife asked to stay for a while. The soft-hearted Ideal looked at his ex-wife with the child and couldn't refuse. But he couldn't explain to Cai Meng. In order not to arouse his girlfriend's suspicion, Ideal tried every means to raise enough money to buy back the property rights of the other half of the house, but his ex-wife didn't want it. She took out an agreement and asked Ideal to be the temporary father of the child for three months. If Ideal was willing, at the end of the agreement, his ex-wife would give up the property rights of half of the house and fly away. This agreement made him excited and headache. After signing the agreement, he was forced to perform his duties. Han Qing was very dissatisfied with Ideal's continued struggle in Qinqiang, and wanted to use modern life concepts to prove that Ideal's approach had no way out. Ideal is that you can say anything, but she will get angry with anyone who says Qinqiang is not good. But in life, Ideal thinks that Han Qing has returned from hard times and is very tolerant. In the eyes of outsiders, they look like a real couple, which arouses Caimeng's dissatisfaction. Due to Zhicun's reminder, Ideal suddenly feels that Dazhi may be her child, born after their divorce. Ideal secretly takes the child to do a paternity test, but the plan is ruined because of incomplete procedures. Ideal's mother, who has a heart disease, learned that Ideal has a child and came to visit. The mother originally liked Han Qing very much. They did not tell her mother about the divorce, so Ideal had to lie to her mother that the child was hers. Ideal is determined to attract investment to rehearse a new Qinqiang opera and participate in the national rehearsal, but it is very difficult. Manager Cheng, the owner of a company, is willing to invest in the troupe because he is fascinated by Caimeng's play, but Caimeng is frequently invited to participate in the manufacturer's commercial activities, which arouses Ideal's dissatisfaction. Caimeng believes that Ideal has given up the dream of revitalizing Qinqiang and is also very dissatisfied. The relationship between the two is in crisis. Han Qing, the ex-wife, left the child and Ideal, who had no experience of being a father, and suddenly left. Ideal was in a mess. Cai Meng couldn't bear to let the child suffer, so she helped Ideal cook. Seeing Cai Meng playing happily with the child, Ideal was very moved. Han Qing returned and saw that the child and Ideal were already as close as father and son, and was also very moved. Knowing that Ideal's ex-wife returned with a child, Cai Meng's parents were very angry and forced them to break off the relationship immediately. On the weekend when she returned home from the Qinqiang Opera Troupe, Cai Meng was locked in the room by her father and refused to meet Ideal. Manager Cheng, who came after hearing the news, was very popular with Cai Meng's parents. Ideal became more and more convinced that the child was his own, and he wanted to persuade Cai Meng to fight for the child with him to raise together. This annoyed Cai Meng's parents even more. Manager Cheng was arrested for misappropriation of funds. The half-rehearsed play stopped again due to lack of investment, which made Ideal very distressed. At the critical moment, rumors spread in the troupe that Caimeng had obtained the funds by sleeping with the boss. Caimeng could not stand Ideal's questioning and the blow of rumors, and left the troupe in despair to sing in the bar. Ideal went to the bar with great effort, and tried to impress Caimeng with tears and go back to the troupe to continue to realize her dream. Caimeng did not listen. When Ideal insisted on filming the play, his ex-wife Han Qing stood up to dispel the rumors for Caimeng. At this time, a huge donation suddenly returned to the troupe, indicating that the donation was for the revitalization of Qinqiang. Ideal regained confidence. In order to let Caimeng, who played the leading role, return to the troupe, Han Qing personally went to Caimeng's house to do her work and told Caimeng all her true feelings. It turned out that Ideal's ex-wife Han Qing was already the chairman of a large company, and she was in the late stage of cancer. She raised a female colleague who died accidentally and left Dazhi, an orphan. She knew that her ex-husband Ideal was kind-hearted and wanted to entrust the child to him. In fact, she had arranged everything for Ideal in the future. But when she tried to change her ideal life, she failed. She was moved by Caimeng and Ideal's desperate persistence to revitalize Qinqiang. She saw herself in Caimeng. So she decided to devote all her financial resources to fully support the Qinqiang career she had fought for. Caimeng was deeply moved by Han Qing. A man named Shi Hu suddenly appeared and said that the child named Dazhi was his biological son. He sued Han Qing in court for custody of the child. The facts were clear that Dazhi was indeed Shi Hu's child. But Han Qing could not forgive Shi Hu for abandoning his female colleague that year, and was desperate to retain Dazhi's custody. However, Han Qing, who was terminally ill, could no longer support the court hearing. Ideal and Caimeng found Shi Hu and took out the letter Han Qing wrote to Dazhi every birthday, which he had written until Dazhi was eighteen years old. Han Qing's love for Dazhi moved Shi Hu, and he gave up the lawsuit and settled. Finally, Han Qing left the world with peace of mind.
