Well....intensity. Wowcha, someone get me a bucket. The male lead (emperor) was just so on point, the actor who played him was fantastic. Brooding, dangerous, possessive and utterly smitten with the female lead. The female lead was strong, smart, beautiful - she was the perfect heroine in my eyes. The plot was very thick to me, and sometimes it was easy to become lost in it. However, there were plenty of romantic scenes and I kept going back just to rewatch certain bits as they were just so beautifully done I loved this drama so much. One of my top favs. I'm already thinking about watching it again. Great show, great actors... I highly recommend it if you're into possessive, powerful and dark heroes!
