Jiang Minzai (Jin Zaiyuan): He is calm and kind at heart. As the adopted son of his mother, Ms. Jin, he obeyed her last wish, gave up his ideal and became a surgeon. When his mother repeatedly urged him to get married, Min still remembered his former lover, so he made Zhenmin pretend to be his fiancee, hoping to cheat his mother, but in the end he really fell in love with her. What's even more unexpected is that my younger brother Cheng Zai also fell in love with this 19-year-old future sister-in-law, which made it sensitive and contradictory. Han Zhenmin (Zheng Duobin): The daughter of Zheng Junxi, the owner of a construction company, is cheerful and lively, even a little savage. At the age of four, my father lost his memory in a car accident and never heard from him again. In order to seize the property left by her mother, the aunt who lived together threw the young Zhenmin on a distant train. After that, Zhenmin was adopted by a fisherman. After the adoptive parents left one after another, she and her brother Jiang Biao lived alone. For Jiang Biao's high medical expenses, Zhenmin had to drop out of school to do various jobs. After meeting Min Zai, the younger brother's attending doctor, Zhen Min fell in love with him secretly and became his contract fiancee by mistake, and her unhappy brother-in-law also fell in love with her. When Cheng Zai left for America, she found that it was Cheng Zai who worried her deeply. Jiang Shoudai (Gye-sang Yun): Min Zai's younger brother, contrary to his brother's submissive character, is a rebellious guy who often runs away from home to resist his mother's oppression. His mother wanted him to study management, but he had a soft spot for mathematics and eventually went to the United States to study mathematics. I fell in love with this future sister-in-law. Cui Xiuzhi (): Ms. Song's daughter lives with Zhen Min's family. She is very beautiful, talented and calculating. Family reasons cultivated her inferiority and vanity. Because my mother is a widow, I have always envied Zhenmin for having a kind father, Jun Xi. 19: 00, Zheng Xi found her and asked Zhen Min. She concealed the truth, hoping to monopolize Zheng Xi's father's love and get his help in her career. Because she loves Zhenmin deeply, Xiuzhi opposes Zhenmin everywhere. Finally, when everything was revealed, I finally understood that I wanted to get my innocent eyes back. A group of young people who want to join this society after graduating from college struggle alone. "Long-term economic stagnation has made the number of unemployed young people as high as 400,000 ..." It is really difficult for young people who are full of rebellious consciousness and do absurd things to become a member of this society. However, his dream is to be a person who is not for money or pursuit. In a cherry blossom season, he suddenly disappeared. As the son of a big consortium, he married a female worker against his father's wishes and gave birth to Hewon. Love his wife and daughter more than a man who loves himself. One day, because of my mother's disappearance, I was on my way back to my hometown after leaving for 6 years, so I suddenly disappeared and completely lost contact. Pak Yonran couldn't stand the blow and fell down. I can't even believe that my husband lost the news. I can't believe that he just abandoned their mother and daughter. Yumin and Jane are not brothers and sisters. Yumin was adopted by KanPyo's mother who worked in the canteen after the orphanage and raised her as her own daughter. Later, my father's fishing boat was killed by a typhoon. And the mother who couldn't stand the hard life any longer ran away from home with her savings. On the other hand, Yumin became KanPyo's only relative. KanPyo has been suffering from kidney disease since childhood. Yumin takes KanPyo back to Hancheng Hospital for treatment every month. . . ) But whenever I want to go to the hospital and see Sister Min, Yumin will be very happy. Minjie is a hospital intern who Yu Min began to have a good impression on him a year ago. Yumin is like a lovely stalker around Min Jie. Later, he pretended to be a student at Minjie University. Although he occasionally feels uneasy, he has become a natural encounter with Minjie not only in the hospital but also in the school. Although Sister Min knows that Yumin likes herself and is a little touched, she doesn't accept her like other girl friends. Min Jie was moved by Yumin's innocence, but she couldn't open her heart to Yumin because she had an unhealed wound in her heart. . . The famous "hungry mathematician" worked hard for this dream and eventually became the most successful young man in the family.
