In "21st Century Grand Duchess," IU and Byun Woo-seok shared a kiss on a yacht.
According to Nielsen Korea, a ratings survey company, the sixth episode of the MBC Friday-Saturday drama "21st Century Grand Duchess" (script by Yoo Ji-won, directed by Park Jun-hwa and Bae Hee-young), which aired on the 25th, recorded 11.3% in the Seoul Capital Area, 11.2% nationwide, and 5.9% among viewers aged 20-54, ranking first among all Saturday programs in the Seoul Capital Area and among the 20-54 demographic. The nationwide and 20-54 viewership ratings not only set new series highs, but the scene where Seong Hee-ju (played by IU) tells Prince Lee An (played by Byun Woo-seok), "Do whatever you want," soared to a peak of 13.4% per minute.
On this day, Seong Hee-ju and Prince Lee An, who drew attention by attending the state banquet together, also displayed a unique presence in the second act of the banquet. Earlier, Prince Lee An had asked Yoon I-rang (played by Gong Seung-yeon) to give up his marriage to Seong Hee-ju and instead invite her to the state banquet. Yoon I-rang assumed that Prince Lee An's arrival with Seong Hee-ju was merely a parting gift and allowed a stage reserved only for the two of them.
However, Prince Lee An surprised everyone by presenting his mother, Queen Dowager Ui-hyun (played by Kim So-hyun),'s ring to Seong Hee-ju and proposing to her in front of all the guests. Seong Hee-ju, who received the unexpected proposal, happily accepted Prince Lee An's proposal and achieved the remarkable feat of securing the approval of King Lee Yoon (played by Kim Eun-ho) without delay. As a result, Seong Hee-ju and Prince Lee An became a betrothed couple recognized by the king.
Prince Lee An's surprise proposal drew attention not only from domestic media but also from foreign outlets. Yoon I-rang, caught off guard by Prince Lee An's plan, judged that she could not overturn a royal decree once issued and decided to accept the marriage between Prince Lee An and Seong Hee-ju. Not wanting to cause a split within the royal family and the cabinet, and having promised to support Seong Hee-ju, Prime Minister Min Jeong-woo (played by Noh Sang-hyun) had no choice but to support the couple's marriage.

To successfully complete their contract marriage, Seong Hee-ju and Prince Lee An secretly and decisively drafted a formal contract, officially beginning their marriage preparations. Their bickering while negotiating the contract terms brought smiles to viewers.
Amidst this, an awkward dinner between Seong Hee-ju, Prince Lee An, and Dowager Yoon I-rang took place, heightening the tension. Yoon I-rang, who initially appeared gentle and eased the guard of Seong Hee-ju and Prince Lee An, gradually revealed her hostility toward Prince Lee An. Seeing Prince Lee An remain silent despite his sister-in-law's rude remarks, Seong Hee-ju suddenly took his hand and led him away.
Prince Lee An said, "As long as we are married, I will handle whatever is in front of the house," and after looking deeply at Seong Hee-ju, who got angry on his behalf, he smiled and asked her to take him away instead. In response, Seong Hee-ju prepared a yacht for Prince Lee An, gifting him a moment of free escape so he could set aside his worries, even if just for a while.
The two spent a happy time on the yacht, feeling as if they were flying in the sky. And in the blink of an eye, as they found themselves in close proximity, Prince Lee An kissed Seong Hee-ju's lips, savoring a romantic moment. Seong Hee-ju also gently pulled Prince Lee An closer, sharing a loving kiss on the yacht.
