The Cold-Blooded Crown Prince’s Double Life

The most feared man in the Joseon palace, Crown Prince Yi Hyeon, known as a tyrant, has a secret no one knows. Before the ministers he is a cold-blooded politician without mercy, but the moment he opens the doors of the Eastern Palace, he becomes someone entirely different. Another face appears only before his beloved family, especially Crown Princess User and their two children. There, an absurd palace parenting diary begins.

Love at Opposite Extremes That Shakes the Palace

When he wears the red royal robe, Crown Prince Yi Hyeon radiates authority no one can defy. Yet he has one weakness: nine-year-old crown prince's heir Yi Jun and his nine-month-old youngest princess. He is strict as a tiger with his son to raise him as a future king, but before the crawling princess who bites memorials, he becomes as meek as a lamb. This outrageous favoritism quietly shakes palace peace again today.

The Clever Heir and the Tiny Trouble-Maker Strike Back

Always dressed neatly as the heir and trying to act dignified, Yi Jun sometimes feels hurt by his father's favoritism. Meanwhile, the youngest princess with chubby cheeks and soft baby hair roams the palace and causes endless trouble. Between severity and devoted love, the siblings are sometimes touching and sometimes funny.

Wisdom That Orchestrates Warm Chaos

The one smiling at the center and balancing all this chaos and dramatic emotion is Crown Princess User. Laughter, empathy, and the noisiest yet warmest family story bloom in the middle of the cold palace. The crown prince's secret parenting diary begins now.

TIP

Rather than treating the heir simply as a child, lean slightly toward seeing him as someone who may one day become king. Letting him choose for himself and bear the result naturally leads play toward situations and consequences more than emotion.
