The marriage between Su Wan (cardiac surgeon) and Lu Shiyan originated from family origins (both parents were lovers who were forced to separate), but it was full of misunderstandings due to Lu Shiyan's preference for "White Moonlight" Lin Weiwei: Su Wan signed for Lin Weiwei's surgery and was accused of "ulterior motives". When she filed for divorce, she found out she was pregnant, but she fainted and miscarried, and her mother also died of a critical illness. In the end, Su Wan was heartbroken and went abroad to study.
Five years later, Su Wan returned to China as hospital director and reunited with Lu Shiyan, who was already a competitor in the medical industry. Lin Weiwei's hypocrisy was gradually exposed - she forged evidence of Su Wan's "marital infidelity", engineered Su Wan's miscarriage, transferred Lu's assets, and even murdered Su Wan's mother. After learning the truth, Lu Shiyan fell into regret and started the "Wife Chasing Crematorium", while Lin Weiwei eventually jumped off a cliff and died due to extreme behavior.
Su Wan gradually let go of the past, married and had children with Lu Shiyan, and jointly established a heart relief fund to help others. However, happiness was short-lived: her son was diagnosed with family hereditary cardiomyopathy, Lu's mother passed away, Lu Shiyan lost his memory due to brain tumor surgery, and Su Wan was diagnosed with advanced lung cancer. In the end, his son and Su Wan passed away one after another. After Lu Shiyan recovered his memory, his excessive grief also disappeared. The three of them were buried together. The tombstone was engraved with the words "The deep love that eats away at the bones will eventually turn into ashes; the regrets in this life will be repeated in the next life." This tells the story of the misunderstandings, belated love and irreparable regrets between the two in their lives.
During the process, Gu Yanchen (Su Wan's senior and partner) always supported Su Wan and became a warm background in the emotional entanglement between the two; the plot of the fund rescuing patients also added a glimmer of life to this sadistic story.
