For people who hate the female lead Soo Jung. It's only at the beginning. I swear as the story progress, it will get better. :)
I was also questioning her actions at the beginning at the story. However, as it is revealed the next few episodes, she was just young back them and didn't really understand the effects of her actions. Also, she was not totally at fault.
I think a lot of people misunderstood the drama. From episode 1, it seems like it was Won telling his story to San. "This is the story of ME who came to love YOU more than myself". After 7 months he stepped down as King and went to San who waited for him and stayed in Goryeo.
I think the whole drama was misunderstood by a lot of people. It was an open ended drama in which people are free to think who the girl ended up with. For me, she may have left with Wang Lin, however, it is not said that she stayed with her. I think the scene in which Wang Lin admitted that he should have never love San, and promised that he will never touch her again made me convinced that he gave up on her because he lusted for another man's woman. Also, after several months, Wang Won stepped down as a King and is free to love whoever he loves. And, Eun San stayed at Goryeo waiting for her true love, Won.
