In 1925, Xia Ziying, who was only fifteen years old and born into a medical family, was decisively sent by her father on a ship to the other side of the ocean two years after her mother passed away, and began a ten-year life in a foreign country. Ten years later, Xia Ziying decided to put aside her hatred for her father and return to China, but was once again blocked by her father. In the past ten years, Xia Ziying's attitudes have made Xia Ziying more confused and strengthened her belief in returning to the country. But after returning to China, Xia Ziying discovered that her father Xia Yunyang had remarried, and her stepmother was the young and beautiful Xu Menglin, who was a few years older than herself, and she had an eight-year-old son. The subtle relationship between her father and Xu Menglin made Xia Ziying suspicious. Xia Ziying found it unreasonable that her father would not let her get involved in the family's medical affairs, and even arranged a marriage for herself, hoping to use this marriage to allow her to immigrate abroad. Xia Ziying had no choice but to enter the laboratory of Jinyang Medical University as an associate professor, where she met Gu Litian, who was also an associate professor. The sudden death of her father brought Xia Ziying back to that home. At the same time, her mother Cheng Jin, who had been dead for twelve years, came back to life and reappeared in front of Xia Ziying. A series of events made Xia Ziying aware of something strange and began to investigate. As a result, a shocking conspiracy was placed in front of her. Therefore, Xia Ziying accepted the marriage arranged by her father before his death, and started her own plan by using the power of her husband's family. Can Xia Ziying successfully smash this shocking conspiracy? When the truth is revealed, what will be the fate of those who truly love her? We are all a drop in the ocean. Those fireworks caused by encounters, even if they are only for a moment, are enough!
