The unpopular third princess of the Rong Kingdom was humiliated in every possible way by the royal family of the An Kingdom. She was even treated as a worthless abandoned son of a married woman and sent away to a foreign country. But no one knows that this princess, who seems to be at the mercy of others, actually has a hidden edge and a lot of troubles in her chest. On the way to the marriage, she unexpectedly discovered the shocking conspiracy of her biological father, the regent - the so-called marriage was just a pawn for him to consolidate his power and sacrifice his daughter. In a desperate situation, the three princesses secretly contacted the loyal and brave forces in the DPRK and the Central Government, and worked step by step to wait for an opportunity to counterattack. When the time came, she turned the tide in the chaos of the palace, shattered the regent's ambition to usurp power, and took charge of the Rongguo government with her own hands.
