In "21st Century Grand Duchess," IU's character requests a divorce for the sake of Byun Woo-seok's character.
In the ninth episode of MBC's Saturday-Sunday drama "21st Century Grand Duchess," which aired on the 8th, scenes were depicted featuring Seong Hee-ju (played by IU) and Prince Lee An (played by Byun Woo-seok), whose contract marriage was exposed.
Following the revelation of the contract marriage that day, an article emerged claiming that Seong Hee-ju's collapse was staged, and public opinion grew fierce in calling for Prince Lee An's removal from his regency. Prime Minister Min Jeong-woo (played by Noh Sang-hyun) also requested that Prince Lee An step down from his regency.

Five days before the contract agreement was leaked, Min Jeong-woo received a report that Digeoksin was detected in a wine cup during the investigation into Seong Hee-ju's collapse at the wedding ceremony. Through Ah Ah-reum (played by Choi Ji-soo), Min Jeong-woo learned that the mastermind behind the plot was Yoon Seong-won (played by Jo Jae-yoon), the father of Yoon I-rang (played by Gong Seung-yeon). Min Jeong-woo then confronted Yoon I-rang and applied pressure. Subsequently, Yoon I-rang handed over the marriage contract between Prince Lee An and Seong Hee-ju to Min Jeong-woo, swaying his resolve.
Meanwhile, Yoon Seong-won visited King Lee Yoon (played by Kim Eun-ho), pressuring him to take action against Prince Lee An. Witnessing this, Prince Lee An grabbed Yoon Seong-won by the collar, saying, "How dare you threaten His Majesty?"
Prince Lee An said, "I am sorry for showing Seong Hee-ju such a sight," and Seong Hee-ju encouraged him, saying, "You did well. To protect anything, one must attack the attack." However, while watching Prince Lee An sleep, Seong Hee-ju confessed her true feelings, saying, "I am also afraid. I am afraid I might ruin the royal house."
Seong Hee-ju then visited her father, Seong Hyeon-guk (played by Jo Seung-yeon), knelt before him, apologized for her mistakes, and asked for his help. Upon returning, Seong Hee-ju embraced Prince Lee An and surprised him by saying, "Prince Lee An, let's divorce."
