That OST blew my mind!!!! Just like the rest of the drama. Acting wise it's the best Haneul, Lee Joongi, and IU did a fantastic job obviously but even the supporting cast everyone from Nam joo hyuk and Ji soo to Baekhyun did a great job but ok special mentions to Hong Jong Hyun who seriously acted so well nothing like his previous roles. He was able to bring the conflicting emotions of his character from being a little bit of a narcissist in the beginning to becoming someone obsessed with power and when you realize he keeps himself looking like a villain but how inside its driving him slowly insane. And this actor he delivered so we could see all these disparate sides of him he's a different person when he was just hanging out with his brothers even if he was a little misguided and how because he felt wronged by someone who was always tagged as a villain by his mother even though they're biological siblings.

At the same time I think IU played her character with a kind of innate innocence which never comes across as childish but merely naive especially considering the time period she's in. I think she beautifully portrayed the emotions of her character, whether it was happy or sad or heartbroken. I honestly fell in love with her in this drama.

Lee Joongi ok again another actor who is so talented at portraying a range of emotion and seriously Hanuel is my favorite no doubt but the second Lee Joongi steps in you feel his presence it completely takes over every single scene. And I honestly started rooting for them the second he stepped in and I was put through hell.

Hanuel ok because he played the character with such nuance I was able to despise him lol that's a good thing! And I truly love the way he showed the conflict in his character and made it come alive.

Special mentions to Park Ji Yong for playing her character so damn well and giving us a villainess worth hating and same for Kang Han na who played Yeon Hwa and truly made her character come to life.

Ji Soo and Nam Joo hyuk did great as the supporting cast I absolutely loved their antics and their bromance with each other and with the other princes was so amazing it became heartbreaking.

Another two members of the cast who also made the drama what it is and gave you everything from comic relief to sheer tragedy was Baekhyun and his character prince Eun and his romance with Z hera as Soon deuk! Omg I watched their adorable back and forth again and again.

And I know a lot of people go "idols can't act" and that's such a moronic thing to say as though acting is some kind of special club that you have to take membership in order to act lol like wtf does anyone's job description have to do with their acting skills? Would you tell a library assistant she can't draw? Like ok that is the most elitist bs ever! And I know a lot of people are art elitists but I don't support them because I'm not a douche.

So idols can act and should act and they shouldn't care about a bunch of elitist pricks.

Anyway so yes Baekhyun's role in the beginning was comic relief and rather easy but gets so much more complicated later because of the way the plot progresses. And wow he delivers.

So, am amazing drama about good and evil and insane kind of love.
