After binding to the System, she gains her freedom. The System tells her she must successfully win over the male leads in five worlds before she can truly be free.
So Duan Yaorong transmigrates through time and space to win the male leads' hearts. Cold and unfeeling by nature, she understands nothing of human emotions, yet falls in love with others without even realizing it. In the end, she is brutally betrayed, and from then on vows never to love anyone again.
