Waking up from a deep sleep, Grand Princess Zhaoning unexpectedly finds herself transformed into Yun Li, the vicious fake young lady in a script who miserably dies by hanging. With the letter of divorce in hand, she neither cries nor makes a fuss, instead turning back to storm the Marquis's estate, seizing evidence, dismantling plots, and casually provoking a cold-faced general, a down-and-out younger half-brother, a mysterious prince, and a haughty heir. Little does she know that the moment she pulls all four men into her game, assassins and undercurrents of imperial power follow hard upon each other's heels. In this lifetime, she is determined to rewrite her destiny and make everyone play by her rules.
