IU, the “21st Century Grand Prince’s Wife,” makes the decision of a lifetime to protect the man she loves, Byeon Woo-seok. She decides to kneel before her father, Cho Seung-yeon, who has been both her pride and her only wall.
In the 9th episode of the MBC Friday-Saturday drama ’21st Century Grand Prince’s Wife’ airing today (8th) at 9:50 PM, Seong Hee-joo (played by IU) is seen fighting desperately to protect Grand Prince Ian (played by Byeon Woo-seok) amidst a critical crisis: the leak of a prenuptial agreement.
Previously, Seong Hee-joo fought hard to overcome the limitations of being the illegitimate child of Castle Group Chairman Seong Hyun-guk (played by Cho Seung-yeon) to get her abilities recognized. However, her relationship with her father always remained distant, and she was often hurt by his cold acknowledgment.
But this time is different. When the prenuptial agreement with Grand Prince Ian is leaked, threatening his status and safety, Hee-joo decides to tear down all the walls she built for herself. In the released stills, Hee-joo visits her family home and kneels before her father, shedding heartbreaking tears. She bows her head to her father for the first time in her life, driven solely by the desire to protect Byeon Woo-seok.

The atmosphere at the family home turns ice-cold due to Hee-joo’s sudden actions. Not only Chairman Seong Hyun-guk, who maintains a cold expression, but also her brother Seong Tae-joo (played by Lee Jae-won) and sister-in-law Han Da-young (played by Chae Seo-an) cannot hide their bewilderment at Hee-joo’s desperate plea.
A key point to watch is how the subtle fatherly love Seong Hyun-guk showed toward his daughter, who entered the unfamiliar place called the palace alone, will act as a variable in this crisis, especially since he had previously ignored her achievements. Tension rises as fans wonder if the father, seeing his once fierce daughter’s tears, will become a strong ally in protecting the Grand Prince or if he will strike another blow.
The production team stated, “As Seong Hee-joo’s feelings for Grand Prince Ian deepen, her actions will become more bold and sacrificial.” They added, “Please look forward to IU’s overwhelming emotional acting as she goes to any lengths to protect someone more precious than her own pride.”
