A synopsis of the story after repeated reading

Zheng He Zheng is a sister. Athena Chu lived in the country with her grandmother since she was a child. When she was brought back to Seoul, her sister Kim, who was one year older than her, couldn't hold her. They often have friction. They don't like her mother, Zhen Zi, and always prefer Kim. After graduating from Athena Chu College of Nursing, she worked as a nurse in an Asian hospital. She is enthusiastic and capable, and is deeply loved by patients and colleagues. Once, Athena Chu was pickpocketed by a thief in a subway station, and the young prosecutor Park Ji-sung bravely subdued the thief with the police. After several exchanges, the two developed from acquaintance and respect to mutual affection. Park Ji-sung is honest and successful, and is highly praised by his family and society. Because he is the eldest son, his parents attach great importance to his marriage.

Under the pampering of her mother, Zhu Jin developed many bad habits, such as vanity and femininity. Although I have a master's degree, I can't write novels or work to teach children. She is very picky about marriage and hasn't talked about anyone so far. Park Ji-jung's younger brother Park Ji-feng works as a dance coach in a TV station. He is a fashionable young man. He has curly hair, earrings and a lazy life. He always smiles when he is taught by his father. When Ji Feng saw Zhu Jin on TV, he ran after her and asked her address and telephone number. In their mutual communication, Zheng Ji and Athena Chu, Ji Feng and Zhu Jin lived the life of lovers intimately.

When Zheng Ji and Ji Feng were with their fiancee, they found that they were sisters. Grandma Zheng Ji doesn't approve of two brothers marrying two sisters. She hopes that one of them will break up, and they are not allowed to kiss each other. Ji Feng made it clear that a wedding date had been set. When his parents saw this, they had to make Zheng Ji give up Yinzhu. After being forced to break up, Zheng Ji and Athena Chu couldn't eat, and Athena Chu fainted in the hospital without eating for three days. Zhu Jin decided to give up her marriage with Ji Feng after seeing her sister's grief over breaking up. The children's true feelings finally touched grandma. She finally agreed to the couple's marriage. After Zhu Jin and Athena Chu got married, Athena Chu did all the housework. At first, Athena Chu was very upset. Finally, through her own efforts, she won the love of the whole family, and her mother-in-law also paid for her to go to college. A few years later, Athena Chu and Zhu Jin both successfully gave birth to children, and the family lived a happy life.
