Ballet, angels, forbidden love, sacrifices and a damn wicked OST. The writers really didnt want to leave much out. And the acting by both leads ?, Especially Shin hye sun. Her acting chops just keeps improving. After watching her in hymn of death with Lee jong suk, had to give this series a try and am so glad I did. Became an instant fan. Yep, will be following her career and supporting her acting growth. Fighting! First time watching Kim myung soo. Not usually a huge fan of kpop singers dabbing in acting as most just gives a mediocre performance but he did pretty good. All I can say is when you mix in a well written script, well picked casts that delivers in performances, beautiful cinematography carrying out the scenes and then ties it all up with an amazing OST - you just stumbled upon a Gem. Only slight criticism is I wished they could have oomphed the ballet pieces a bit more. Would have added a dash of excitement to the series.
Conclusion: Human - Angel forbidden love. Then struggle, struggle and then struggle some more to overcome adversity, all while still making sure the story and the plot stays interesting and at point. Give this series a watch. Go!!
