Katrina, working as a servant in the household of Count Sashaval, endures brutal abuse due to certain circumstances. One day, she is sent to Prince Clarence, the "cursed prince" rumored to be cold and heartless, as a substitute for Charles. Deeply scarred by years of abuse, Katrina cannot hide her fear even in the luxurious mansion. Amidst this swirling despair and anxiety, she finally meets Clarence, the master of the house, for the first time. The destinies of the substitute young lady and the lonely prince begin to quietly unfold.

Clarence openly expresses his disgust at Katrina, who is drenched in the blizzard, calling it a "sympathy-seeking act." However, instead of drying herself, Katrina desperately wipes the wet carpet, begging for forgiveness. Feeling uneasy about her unusual fear, he catches her when she collapses with a high fever, and is astonished by how light she is. Disarmed by her innocent reaction upon waking, he becomes certain: this girl is not the "arrogant Charles" he has heard so much about.

"If you don't work, you won't eat," Katrina said, trembling, as countless scars etched onto her body. The painful truth and her words and actions were too much for Clarence to bear, and he embraced her. "There's no need to apologize, just tell me your real name." Pierced by his unwavering gaze, Katrina revealed her name, trembling, and he gently told her, "I want to get to know you." Surprised but relieved to finally have a place to belong, Charles, who had learned of her survival, was seething with a dark desire for revenge.
