Divorce Crisis, Abdication Edict, and Palace Fire Ending
Episode 10 follows Sung Hee-joo and Grand Prince Lee Ahn after the contract-marriage scandal. They try to separate in order to protect each other, confirm their true feelings again, and then fall into a larger political crisis when an abdication edict and a palace explosion shake the royal court.

With Lee Ahn said to be inside, episode 10 ends on a fire cliffhanger that raises the tension for episode 11.

Episode 10 Story Recap
1. Sung Hee-joo chooses divorce to protect Grand Prince Lee Ahn
At the beginning of episode 10, Hee-joo makes up her mind after hearing her father’s advice. The idea that she is Lee Ahn’s only weakness hits her hard, and she decides to step away while carrying the scandal herself.
This divorce does not mean the end of love. Because she loves him so much, she fears that staying beside him will make him more vulnerable. Her declaration is closer to painful protection than a cold breakup.
2. Sung Tae-joo’s press conference shakes public opinion
With criticism growing inside and outside the palace, Sung Tae-joo changes the flow through a press conference. He frames the contract issue as something he did while trying to protect his sister, loosening the blame aimed at Hee-joo and Lee Ahn.
This scene stops Hee-joo’s plan to fall alone. Tae-joo’s intervention creates space for the two leads to find their way back to each other.
3. Lee Ahn asks the king to return his place
Lee Ahn also refuses to retreat. He asks King Lee Yoon to return what belongs to him, marking the moment when a man long treated as a dangerous variable chooses to step forward himself.
King Lee Yoon connects the situation to the late king’s will and issues an abdication edict. The story expands from a romantic conflict into a political event about succession.

4. Hee-joo and Lee Ahn confirm their true feelings again
Worried after Lee Ahn leaves the palace, Hee-joo searches for him. When they meet again, she confesses that she likes him and explains that she suggested divorce because she wanted to protect him.
This reverses the emotional wound of episode 9. They tried to protect each other by pushing each other away, but they finally realize that standing together may be the only way to endure.
5. Lee Ahn’s confession: he wanted to protect his nephew, not simply become king
Lee Ahn tells Hee-joo why he is moving toward the throne. He says he wanted to protect King Lee Yoon, his nephew, but he also wonders whether the idea of saving everyone has become his own ambition.
Hee-joo tells him to want it and to go all the way. Her words sound like a promise that he no longer has to carry the burden alone.
6. Yoon I-rang’s past and Min Jung-woo’s pressure
Episode 10 also reveals Yoon I-rang’s past. She once had feelings for Lee Ahn, but she gave up both her dream and her heart to become Crown Princess. Seeing Lee Ahn appear to lose nothing leaves her with anger and resentment.
Min Jung-woo then pressures Yoon I-rang by mentioning the custom of rejecting an abdication edict three times, pushing her to act before the remaining procedure ends. This makes him look less like a helper and more like someone moving the board from behind.

7. The council hall explosion puts Lee Ahn’s life in danger
