The story of Princess Pyeong-gang is the basis for a historical drama that stars Song Su-jeong, a top celeb with a huge ego and a foul mouth.

Talking with the man she meets in the jail cell, Su-jeong realizes something is amiss and checks her script about the tale of Princess Pyeong-gang.

On Dal lives for money. But no matter how hard he tries, he's always broke. Every night, he wishes upon a star for one big chance to make him rich.

Handling Su-jeong's temper is her manager, Byun Sam-yong. His efforts made her into a star, and because of him, she becomes Princess Pyeong-gang.

Princess Pyeong-gang is King Pyeong-won's only child. She loves to read, and in one book, she learns that a strange bird will come to take her away.

Raised on her grandma's tough love, Su-jeong is a strong woman. Even for her, though, this world is a scary place. To "help" her through is On Dal.

Mu-myeong, a person of lowly birth, does not speak. The only one who understood him was Princess Pyeong-gang. For her, he will even give up his life.

Eldest son of the powerful Ko family, Il-yong is tyrannical and bigheaded. No woman meets his standards, but lately, he keeps hallucinating about one.

Six years after he first joined the historical drama team as a costume car, Boong-boong is on the verge of being scrapped. But now, he has a family.

From the tribal chief of mountain bandits, Princess Pyeong-gang learns of their tragic history. She also sells off her wedding gown to the chief.

Il-yong heads to On Dal's house. While the two are alone, Sam-yong tells Su-jeong that he thinks he has finally found the key to bring them home.

Sam-yong gets angry at Su-jeong. Finding Pyeong-gang alone by the river, On Dal approaches her and explains why he had asked her to stay by his side.

While alone, King Pyeong-won takes out a sword with the mark of a crescent moon, which he received as a gift from On Dal's father 25 years ago.

Il-yong orders search parties to find the "crazy woman." While running away, Su-jeong suddenly remembers On Dal telling her not to go anywhere.

Swordsmen surround Su-jeong and Sam-yong. Pyeong-gang tells Mu-myeong to run away. On Dal asks his mother to go with him to his father's homeland.

While Pyeong-gang is asleep, Mu-myeong comes to her as if in a dream. On Dal tells Il-yong that the king has ordered him to enter the palace tomorrow.

In return for helping On Dal carry out a plan, the king wants him to wed the princess. A prized history book that was inside Boong-boong goes missing.

The king tells Il-yong that the wedding is off, but he will find a suitable wife for Il-yong. However, Il-yong says that he will choose his own wife.

Commanding On Dal to fight in the war, the king hands him a sword, which On Dal immediately recognizes. Sam-yong finds the GPS set to take him back.
