Old Friends Don't Know You

A modern girl, Jun Qingnuo, was betrayed by her lover of three years. After her accidental death, she assumed the identity of the prime minister's daughter and was bound to the system. In order to survive, she must make the powerful regent Gongsun Yuqing truly fall in love with her. At first, she regarded getting close as a task and gentleness as a means. But Gongsun Yuqing was never tempted by her attempts to please him. Instead, he saw her kindness hidden behind her calculations while working side by side to investigate cases and protect her from life to death. Jun Qingnuo finally believed that there was really someone in this world who was willing to respect her, wait for her, and spend the rest of his life with her. Just after the two made an engagement and became husband and wife, the system suddenly changed the mission - she had to destroy this relationship with her own hands, making Gongsun Yuqing hate her to the core, forcing him to cut off his weakness and embark on the lonely road of emperor. On one side is your own life, on the other side is your sincerity that should not be exploited. When love becomes a mission and betrayal becomes a way out, how should she choose? And when old friends forget their past and meet each other again, will anyone in the world still remember that they loved each other that way?
