Although the night of Joseon is filled with the thunder sound, the queen's painful screams can still be heard. Royal Physician and paramedics are also busy trying to deliver the baby from the womb. In the dim sky, two bright stars are clearly visible. However, if you look closely, you will see that one star is slightly dimmer than the other. Soon news came that the twins had been born in the royal palace. However, the king was shocked and angry when he heard that the new born baby is twins. Twins within the Royal Family are an abomination. Is the first grandson of the royal family being share a womb with a girl?

While, the King get angry, lord Sangheon, father-in-law of crown prince said to the King that tonight, the only child born into the Royal Family, is the eldest son of the Crown Prince. No one will know that he was born a twin, so please let your worry subside, Your Majesty.

After that, Lord Sangheon ordered to kill the grand daughter and everyone who know about the born of twins and began a clean-up operation. Although the Crown Prince didn't want to agree to kill, he have no choices and could not disobey his father, the King and finally he had to agree to kill his daughter.

The Crown Princess who couldn't accept her daughter misfortune, she consults with the Royal Physician to hold the breath of the new baby girl to deceive her father to believe the girl is already died after she was born. Lord Sangheon check the girl and after confirming of the death, he left.

Then, the Crown Princess was handed over the princess to the bodyguard and order to taken out of the palace. Thus, the twins who were born on the same day and almost the same time, using the same womb, grew up in different places, one without knowing the other's existence.

However, due to fate, 12 years after the incident, the princess returned to the palace as a court maid and was assigned to do the laundry. The prince grew up as excellent prince which is good in both literature and military skills. Therefore, The King, The Crown Prince and his maternal grandfather give all of their love to prince and his life is filled with happiness.

However, in one day, the twins collided with each other due to a ball. When they met each other, both looked at each other in amazement. Even though they feel strange, the eldest grandson, the prince, and Dami, the lowly born girl as court maid who work in the laundry, did not even think they were twins. At that night, the prince told his mother about the girl who exactly look like him and the Crown Princess stop his son not to talk about this case further and she decided to inquired about this girl. Maybe she is her daughter. She needs to find this girl before her father know.

Shortly after brother and sister meeting, the royal preceptor of the prince was arrested under His Majesty order and due to his maternal grandfather proposal, the prince was not allowed to leave his quarter until the dust settles.

The royal preceptor, who is the master that the prince trust and is fond of. Therefore, the prince could not sit when his favorite preceptor is arrested and finally, he got an idea to swap place with Dami, a court maid to see his preceptor. When the price goes outside, Dami stayed in the palace on behalf of the prince and nobody know about this except from his eunuch, Hong.

While Dami have to pretend as a prince, she began to take an interest in the prince's books and borrowed them. One day, the Dami and Jung Ji-un became friends when Jung Ji-un, the son of the Inspector Jung Seok-jo who is the confidant of Lord Sangheon, accidentally entered the quarter known as the Haunted House. The two become friend because of a book which was borrowed from the prince. While Dami reading the book given by the prince, Dami was shock when she saw Jung Ji-un who accidentally entered the Haunted House quarter. Due to her shock, the book that she reading was fell into water and after that, Jung Ji-un also accidentally fell into water again. Therefore, Dami have to rescue Jung Ji-un. Due to this incident, the two became good friend. Because of Dami's words of praise, Jung Ji-un decided to serve the prince when he grows up.

The peaceful days did not last long. The Crown Princess soon known that Dami was his daughter, and the Lord Sangheon found out that Dami was not dead and therefore, tried to kill her again. However, who knows, the prince who swap place again with Dami to see his preceptor's final journey died in the hands of Jung Ji-un 's father, Jung Seok-jo. The Royal Bodyguard could not protect the prince and could only bring the body back to the palace. At first, the Crown Princess thought that the death body is her daughter and she feel seriously pain and sorry for her daughter. However, later on when she found that there was no needle mark on her neck, she realized that the deceased was her son, the eldest grandson, the prince.

To confirm the condition, the Crown Princess hurried to the prince's quarter and found his daughter pretending to be a prince in a prince's costume. This is the Fate. She could control herself and fell on to the floor. She loses her son and she couldn't let her daughter lose again. Therefore, she made bold decision. As a result, the count maid Dami was disappeared and only Li Hwi, the eldest grandson was existed. Nobody knows that the current grandson is Dami who takes place as his brother role.

(Dami opened her eyes and noticed that she was lying on a soft bed. How was that? Was everything about last night not a dream? She looks around and realized that this is not a dream. She was the prince's twin sister, an unlucky born girl who was ordered to be killed by her own grandfather, the King and Lord Sangheon. Was a girl, who born with lowly status and didn't know her own father and mother really a Princess? The unlucky girl was now still alive and her brother, the real prince was died instead of her. And therefore, she has to take the role of her brother, Lee Hwi.

From now on, she became Lee Hwi, the eldest son of the Crown Prince. A girl who was executed before being even given a name and was not list in the Royal Family Tree became the grandson, Lee Hwi. How strange the Fate is? Her thoughts were cut off by the count maid who bring the water to wash the face. Soon after, the count maids came in serve the prince to wash his face, however, Dami, who had not yet become accustomed to it feel strange. And she also put the bed neatly. When the Court Lady Kim saw this and she signal with her eye not to do and therefore, Dami quickly put the bed sheet and pretend.

The Royal Order that prevents the prince not to leave his quarter had not been revoked, so she had to change her clothes and just need to stay in her quarter. Dami could keep her mind ease due to last night accident. She feels depress, anger, sorrow due to this accident. Being born with a girl is nothing wrong. However, she was ordered to be killed because of a girl. She couldn't accept her grandfather and father allow to kill her. As a result, she could not eat lunch or dinner and just stay with sorrowful stage. When the Crown Princess heard that the prince was not eating anything, she came to the prince's quarter and said.........)

Did you not eat anything all day?

I don't want to.

Eat. Even if rice tastes like sand in your mouth and drink water even if it tastes like bitter medicine. You have to bear it.

I don't want. I hate everything.

If you give up now, it will mean death for everyone around you, including me and you. Everyone.

(When the Crown Princess told like this, Dami could not afford to neglect and try to eat. She didn't want to die anyone again because of her. Just her brother is enough. The Crown Princess was in tear also as she watched the prince, even though he didn't want to eat but try to eat vigorously. She said to herself "Please Forgive this selfish mother daughter. I once lose your brother and if I lose you again, your mother will surely die. Please, please forgive me.

Court Lady Kim and Eunuch Hong who knew everything, were also in tear as they looked at Dami. and the Crown Princess.

After eating, the Crown Princess told to Prince that...)

Starting from now, Court Lady Kim and Eunuch Hong will be taking care of you. So don't worry too much. Your schedule is simple. Every morning, you will go to the King's quarters as well as the Queen's quarters to offer your greetings. And then, you will come to our quarters to greet the Crown Prince and me. And you need to attend Royal Study.

Study...

Don't worry... now that you have no preceptor, it will take some time to replace a new preceptor. In the meantime, I will teach you.

It is my honor, Her Royal Highness

This address must be changed from today. Dami is no more in this world. There is only Prince Li Hwi.

Yeah, mother.

Please take a rest now.......

(Thus, Dami, now became the prince, pretended to be ill during these days and secretly learned the basic manners of a prince and tried to become as same as her brother Lee Hwi.)

(Note: These first few chapter is same as the drama and you may feel bore.)

(The prince learns some basic manners and when her movement become nearly the same with her brother, real Lee Hwi, the Crown Princess allow her not to pretend to be sick and need to start the prince daily life. The prince feels excited to leave his quarter because this is the first time she needs to go out as Lee Hwi. Will her grandfather and Father notice her?

When she arrived at his grandfather's quarter, she found that her father and mother had already arrived. When she sat down in the designated place to pay her respects to her grandfather and grandmother, my grandmother said...)

I was concerned when I heard you weren't feeling well for a while. Are you feeling better now?

Yes, I am sorry to have caused you to worry.

Is it because you've been sick recently? Your sound not as strong as before.

No, it is not, Your Majesty, I am perfectly fine.

(When he said that, he pretended to start coughing....)

It is not good. I wll have one of my people to deliver some tonics to get your energy up. Make sure to drink it every day.

Yes, Your Majesty.

(After talking for some time, the King said.......)

This is enough for morning greetings. You may all leave now. Crown Prince, a new preceptor was appointed for Prince, check it out.

Yes, Father.

(The prince came out of the King's Quarter and on his way back to his palace, he was take wrong path and therefore, Eunuch Hong quickly remind that....)

No, not there, It's that way....

Ahhhh.......

(The court maids are looking strangely to their prince who takes wrong path and so the prince just pretend he notice and turn around and take the right way. After taking short rest, the prince have to go to Royal Study Room to Study. After a long day of reading as first time, the prince feels tired and fell asleep while reading at night. Due to the prince sleepy, he slips and drop the medicine which was given to him by court maid and then the cup is broken. Therefore, the court maid feels afraid and suddenly kneel and said "I beg your pardon, Your Highness. I will go and bring another bowl." Then, the maid, first clean up the broken pieces, however, unfortunately, she accidentally cut her hand with broken pieces. When the prince sees this, he quickly helps the girl and cover the maid hand with clothes to stop bleeding. Then, he call eunuch Hong...

Bok-dong

Did you ask for me?

Get some ointment from the royal pharmacy.

Pardon?

Hurry

At that moment, the Crown Princess came in and saw what had happened, so she ordered everyone to leave, and only the prince and she was left alone. And the prince said...

The cut was deep. Please call a physician for her.

There's no need. This is not your place to worry about her even if her finger is wounded or servered.

She was hurt because of me. I dropped the bowl.

No.

It was her fault. So, you don't need to apologize. You never need to apologize. You are the person who don't need to worry about other people. Think only about yourself. You don't need to care about what others think of you. That's what the "Prince" means. There's no need to show respect to others or feel bad for them. The only people you will show respect to are the King and the Crown Prince. Do you understand that?

But.... why must I do that? That's not how I want to live. It is only fair that I apologize to whoever deserves my apology when I am at fault. No matter what my title may be.

They must know their place. Make them fear you. And don't let them get close to you. This is only way to survive. Do you understand?

However......,I understand.

(Even after her mother left, the prince was left in daze. Eldest Grandson, the Prince! Yeah, now Dami is already death and I become Lee Hwi. I am just pretending to be someone else. Goodbye DAMI....)
