"Ha An Nhien's life was already a series of tragedies, but the day she signed The Devil's Contract with a man named Lanh Thien Phong, hell truly opened its gates.
He is an overbearing CEO, as cold as ice, wielding immense power that shakes the business world. His eyes hold no emotion but pure possessiveness and a burning desire for revenge. Due to a colossal debt, and with her family on the brink of ruin, this intelligent, resilient woman is forced to become a captive, a plaything in the hands of that cruel man.
Through endless nights filled with humiliation and anguish, she is tormented, body and soul. Every touch, every venomous word, stabs at her heart like a knife. He sees her as a mere tool, a substitute, yet he never imagined that the threads of fate would entangle them in an inescapable web of grudges.
As the secrets of the past gradually unravel, as the line between love and hate blurs, can Ha An Nhien escape the 'devil king's' cage? Or will she forever drown in the abyss of love—a place where revenge and lust intertwine—only to realize her heart has been mistakenly given to the very person who destroyed her?"
