Mr. Queen

Working as the President’s chef, a free-spirited man, Bong-hwan, wakes up one day in Joseon Dynasty as a woman named So-yong, who has to marry King Chul-jong the next day.

While finding it uneasy settling into a strict palace life, So-young encounters her dream girl who is the concubine of King Chul-jong. Meanwhile, people start to question her changed personality.

Byeong-in helps So-yong from danger and Chul-jong who sensed the forces behind So-yong becomes suspicious of her. Missing the modern food, So-yong heads toward the royal kitchen and has a fight of nerves with the head chef, Man-bok. To fill the lake with water, So-yong tries her best to fascinate Sunwon in her way.

So-yong becomes enraged that Chul-jong was the one who pointed a sword at her. Unlike So-yong who is determined to return to the modern world, Chul-jong reflects on himself by the unexpected move of So-yong. Byeong-in finds a clue while chasing the trace of the man who threatened So-yong. Meanwhile, Sunwon and Jwa-geun come up with a scheme.

So-yong reveals the truth about her death to save Hwa-jin. It hurts Byeong-in to find out the truth and he doubts if the reason for her suicide attempt was due to Chul-jong. Meanwhile, So-yong suffers a setback in the plan of returning to the modern world.

Chul-jong saves So-yong from the lake and suggests "No touch", however she explodes at him. Chul-jong feels sorry and guilty for So-yong who jumped into the lake again. So-yong becomes anxious as she begins to question the law of soul change after she fails to return to the modern world through the water.

So-yong who started a delivery service in Joseon gets a bit of zest in her life. At that very moment, Bong-hwan returns to the modern world and finds out he is a vegetable. Reversely, So-yong who lost her soul faints and the whole palace gets in shock.

Bong-hwan who woke up in Joseon accepts life with power and wealth, even though he gets to live as a woman. He swears vengeance on Mr. Han, the one who ruined his life. Meanwhile, Chul-jong visits So-yong's house and Hwa-jin who heard the news follows him out of insecurity.

So-yong tries to return to the palace as soon as possible, but Chul-jong asks to stay for another night. He suggests they inspect the people at the street market, in the back of his mind, he secretly plans to find the hidden ledger. Meanwhile, Cho Dae-bi, who was humiliated by Sunwon, prepares for a counterattack.

Chul-jong fails to find the hidden ledger at So-yong's house. So-yong decides to have a concubine to satisfy Sunwon and to keep her gender identity. Meanwhile, a mysterious body is found in the palace, causing a great stir.

So-yong who dreamed about Chul-jong becomes confused about her gender identity. It breaks Mun-geun's heart when he sees his daughter devoting herself to picking a concubine.

Byeong-in resents after he finds out Chul-jong was the one who pointed a sword at So-yong. Jwa-geun carries out his plan to ruin the banquet prepared by Chul-jong.

Chul-jong, who was seriously injured in the explosion on the day of repair, is in a coma. Jwa-geun asks So-yong if she would accept the offer he made in the past, and she jumps into the lake to recall the past. Meanwhile, Byeong-in who was chasing the assassin executes a death sentence to the soldiers, even though there was no positive evidence.

So-yong who is drunk mistakenly thinks of Chul-jong for Hong-yeon and spends a night with Chul-jong. The next morning, So-yong panics and avoids Chul-jong, confused that she can't help growing feelings for him.

So-yong who is moved by Chul-jong who did her a favor hears the truth about the ledger from her father. Determined to take revenge on those who tried to kill her, So-yong suggests Chul-jong they ally. Meanwhile, he feels a strange sense of deja vu of the well he remembers in the past.

Chul-jong talks about his ideal country and So-yong decides to devote herself to his plan using her modern knowledge. Byeong-in feels uncomfortable about the gossip of the two always staying together at night. So-yong who figured out the rank of Chul-jong in political power summons Kim families.

Although everyone is in a festive mood at the news of So-yong's pregnancy, So-yong cannot be fully happy. Chul-jong struggles to find a way to conciliate So-yong who has been acting fussy recently.

Chul-jong leaves to put down the rebellion to protect So-yong. While he is away, Sun-won holds the power again and reinstates those who were dismissed by Chul-jong. Byeong-in proposes So-yong to reconcile with Sunwon for her own safety, but So-yong flatly rejects it.

Byeon-in tracks So-yong who went out of the palace to find Chul-jong who has been missing. Meanwhile, the coronation is being prepared in the palace where both the queen and the king are absent.

Chul-jong and So-yong commence the operation to infiltrate safely into the palace. As the rebellion gets more intense, Sunwon and Jwa-geun tighten the guard.
