Sung Hee-joo ♥ Grand Prince Ian: What ending awaits them in the whirlwind of fate?
The ending scene of episode 10, where Sung Hee-joo discovers Grand Prince Ian is inside a burning pavilion, saw ratings peak at 15.4% per minute, proving the show’s absolute dominance.
While their bond has grown stronger despite various threats, all eyes are on the future of Sung Hee-joo and Grand Prince Ian, whose mutual romance has reached its peak. After overcoming countless accidents and crises, they proudly announced to the nation that they are now a married couple. Although it started as a contract marriage, the two have come to sincerely love and cherish each other while actively supporting one another’s paths.
However, tension is rising as Grand Prince Ian gets caught up in an accident immediately after deciding to shoulder the weight of the crown. Fans are anxious to see if they can protect each other amidst repeating tragedies and enjoy a sweet honeymoon life, and what kind of ending they will meet in the whirlwind of fate.
A new couple is born… What will be the fate of the power-hungry?
Attention is also turning to the changing relationships of the supporting characters, sparked by the ‘Grand Prince Couple’s’ contract marriage.
Choi Hyun (Yoo Su-bin) and Do Hye-jung (Lee Yeon), the closest aides to Sung Hee-joo and Grand Prince Ian, are gradually developing feelings for each other, raising expectations for another chemistry-filled couple.
The relationship between Sung Hee-joo and her family, which was like walking on thin ice, is also slowly recovering. Most notably, as Sung Hee-joo faces various threats, her father Sung Hyun-kook (Jo Seung-yeon), brother Sung Tae-joo (Lee Jae-won), and sister-in-law Han Da-young (Chae Seo-an) are sincerely worrying about and taking care of her, leaving fans curious if a happy ending awaits the family.
The fate of the key figures in politics and the royal family surrounding power is another highlight. Prime Minister Min Jung-woo (Noh Sang-hyun), upon realizing that the Sung Hee-joo he loved has truly fallen for Grand Prince Ian rather than just being in a contract marriage, is showing his claws to win her over, standing against his former best friend, Grand Prince Ian.
On the other hand, Yoon Yi-rang (Gong Seung-yeon), who lived her life swayed by her power-hungry father, is trying to correct her past mistakes so her son, Lee Yoon (Kim Eun-ho), doesn’t suffer the same pain. Curiosity is growing over the ending Min Jung-woo and Yoon Yi-rang will face, as they once joined hands to preserve their positions but are now looking in different directions.
