Noble young lady Katerina tragically died in two previous lives. In those lives, she had fallen for the Crown Prince and the Fourth Prince, only to be betrayed by them in collusion with a "white lotus" maid, leading to the ruin of her family and her own demise. Reborn for the third time at a royal ball, she completely severed her emotional attachments and obsessions. She proactively attached herself to the old Emperor, becoming his Imperial Consort. Using a false pregnancy as a scheme, she lured the princes and the maid to expose their ambitions, collecting evidence of their treason. When the coup d'état erupted, she revealed a secret imperial military token to quell the rebellion, stripped the princes of their powers, and imprisoned the three in a death cell to kill each other. Katerina, now holding imperial power, expanded the territory, surrounded by male consorts and worshipped by officials, fully realizing that only supreme power was a woman's sole reliance.
