I love the OST 'Because I love you' and I think that's the highlight of this drama. A boy famously known as 'Joseon's national treasure' misunderstood situation that messed up situation that caused an abdication of a queen and a little princess Hye-Myung losing her dearest mother. He then lost his memory and got sent of to his grandfather then went to China for further education, as an adult he came back to Joseon and got a job as Prince's tutor. He met a princess accidentally and hated her sassy behavior, he found out later that she's the sister of princely student as he's being introduced, they became friends and towards the end fallen in love to each other. The sassy princess Hye-myung (Oh Yeon-seo) who doesn't have the best reputation among the people. She often sneaks out of the palace in search of her mother that she believed still alive. She wouldn't say anything to anyone including her father, the King, as she saw it that no one would want disgraceful dethroned queen back to the picture.

Pretty simple love story, the current queen and Jung Ki-joon, Left Minister (Jung Da-yeon's father) made this story more twists and interesting plots. Since the current queen was so jealous of former queen, she'd do anything to increase her influential and status...manipulate situation into her benefits. At the end though, she died with her former fiancee that fiercely loyal to her.

Hye-Myung refused the marriage proposal because she'd like to be a physician and intended to go to China for her medical training. One year later, they reunited and she proposed marriage to him. Sweet...sweet....I apparently watched this drama twice without realize it and how much I've forgotten scenes and story. I love (Jang Young-nam) Lady Heo, Gyeon Woo's mother - she's a devoted mother and also very expressive...anyway I love all the OST.
