When poor Chen Mo needs to win the 500,000-yuan prize in a physics competition to save his mother, who has kidney failure, he collides with campus beauty Lin Wanxing on the stairs, and they switch bodies.
He becomes her: a ballet prodigy and a Stanford early-admission student, carrying the secret of a fatal medical malpractice incident caused by her father three years ago.
She becomes him: a physics genius struggling on the brink of poverty and illness, holding the truth about the kidney that was stolen from his mother.
They have seven days. He must perform a deadly dance in her body and get her into Stanford. She must use his mind to win a brutal competition and save his mother.
Yet beneath the cracks in their twin jade pendants lies a bloodier rule: this is no simple body swap, but a sacrifice. Only when the scalpel cuts through skin and the kidney of his enemy's daughter begins to beat inside his mother do they discover that whoever survives will forever bear the sins and life of two people.
This deadly bargain began in hatred, but ends in a union of flesh and blood. When love and guilt course through their veins, who is the true avenger, and who is the sacrificial lamb?
