When the Su family went bankrupt and his father was seriously ill, the down-and-out pianist Su Muyan was forced to sign a three-year agreement to raise money to save his life and became the "cage pianist" of multinational president Lu Shiyan.
Due to his childhood shadow, Lu Shiyan believed that Su's father was the "enemy" who killed his mother, and he was extremely indifferent and controlling towards Su Muyan - he confiscated her freedom and allowed "White Moonlight" Wen Zhixia to make things difficult for her. Even after she got pregnant unexpectedly, Wen Zhixia fabricated evidence to mislead her and forced her to stop Su's father's treatment, forcing her to give up the child.
As Wen Zhixia's conspiracy progressed, Su Muyan not only lost his flesh and blood, but was imprisoned by Lu Shiyan when his father was critically ill, and missed the last time he saw her. When sorting out her belongings, she unexpectedly discovered Lu's father's old letters, and she uncovered the truth about all the misunderstandings: the so-called "betrayal" was just a lie made by Lu's father to protect his son, and Wen Zhixia was the initiator who misled Lu Shiyan and ruined her life.
Desperate, Su Muyan burned all traces related to Lu Shiyan, changed his name and took his younger brother away from home, opened a music classroom in a small town, and tried to use the piano to heal the pain. Lu Shiyan, who learned the truth, frantically searched for her in regret, but only got a "clear" from her.
He punished Wen Zhixia, but he could never get her lost child and father back, so he could only silently protect her in the small town where she lived. This scene started with the imprisonment of hatred and ended with his regret and her indifference, leaving only a period of bone-gnawing regret, proving that some damage, once done, can never be repaired.
