This drama blows my mind. I couldn't stop to cry.

The plot is very interesting with so many different characters. Each of these personalities is very important for the whole plot and you never get bored.

The costumes are beautiful, great cinematography. And the OST is virtuous. I think it is the most beautiful drama music I ever heard. It touches your soul, and you can listen to forever.

Very good choice for the cast. All actors are great. IU (as Hae Soo) and Lee Joon Gi (as 4th Prince) have amazing chemistry.

It is very romantic drama, full of emotions and tears. The 15th episode is very sad. So, the last one, too. You need tissues because you will cry your eyes out.

Most beautiful historical drama I ever watched. I have big interest for history and the drama made me research and read historical books about the Goryeo era.

The drama is unforgettable masterpiece. , 10/10 for it.
