Adopted by the wealthy Shen family at the age of three, Sang Ning has always known she is not their biological daughter. Aware of her status as an adopted child, she treads carefully in the Shen household. She stays obedient and sensible, trying her best to please her adoptive parents and two adoptive elder brothers, who were also taken in by the family.
Yet her constant efforts never win their warmth. Her adoptive parents and brothers remain distant and indifferent toward her all along. When the Shen family’s long-lost biological daughter is found and brought home, everything grows worse. The real young lady repeatedly hurls insults at Sang Ning and frames her for wrongdoings. Instead of standing by the truth, the Shens side with their biological daughter and join in mistreating Sang Ning. Their cruelty leaves Sang Ning deaf in her left ear, forcing her to rely on a hearing aid.
Later, the Shen family steals Sang Ning’s confidential technology for intelligent medical devices. Having drained all the value from her, they cruelly abandon her in an abandoned house. Left alone with no care or medicine, Sang Ning suffers terribly from severe illness. Tormented by pain with no one to turn to, she eventually dies in that desolate place. All her years of caution and devotion end in betrayal and a miserable death at the hands of the family she once tried so hard to love.
