The old piano is Cheng Su's only solace, but it hides the surveillance and conspiracy of his stepbrother Ye Wan. The night he discovered the secret, she was trapped by the piano keys and fell into endless threats.
She tried to contact Lu Zheng to escape, but she was ravaged by him in return. When she finally learned that her mother's fault was the source of his hatred, she was already covered in bruises.
The diagnosis of late-stage gastric cancer became her last courage to escape, but the respite in the seaside town could not escape his pursuit. When the sunset dyed the sea red, she closed her eyes in the white dress she had worn when they first met, leaving only a note: "Ye Wan, let's not see each other again in the next life." And he sat in an empty villa and an old piano, and became her prisoner for the rest of his life.
