Fight the system!
An ordinary girl, Lin Wei, was forcibly bound by the "Villain Girlfriend Development System" and learned that she was living in an urban novel. Her mission was to play the role of the "evil ex-girlfriend" of the villain president Gu Yan. She would encourage him to grow into a black man through constant mischief, betrayal and humiliation. If he failed in the mission, he would be wiped out. In order to survive, she was forced to perform demanding tasks one after another. From the initial indifferent observation, Gu Yan gradually became suspicious that there seemed to be a huge secret hidden behind this woman with contradictory behavior and desperate eyes. When Lin Wei failed a mission and was seriously injured and was hospitalized, she almost collapsed and confessed, but was brutally punished by the system. Gu Yan witnessed her abnormality and began to detect clues that science could not explain.
A dangerous game of suspicion, temptation and invisible manipulation begins. He searches for the truth, and she struggles to survive. In a series of fatal missions and forced confrontations, the two gradually get closer and join hands to fight against the mastermind who controls fate, seeking love and redemption in desperate situations.
