B1A4 Jinyoung shows his action and loyalty in Moonlight drawn by clouds.

The plot thickens as we see the latest episode of Moonlight drawn by clouds that Ra On and Crown Prince Lee Young's happiness ended up in further worries, bloodshed and tears.

Kim Byung (Byung Yeon) leaves a book behind at Young's desk. Well the book basically contains the list of names of the corrupted officials for bribery. While all the evil ministers continue to play dumb however Young confirmed he will investigate thoroughly. With PM Kim and his minions discussing further at home, Yoon Sung just listened quietly only to be advised that they found Hong Kyung Rae's daughter is Ra On. Yoon Sung is astounded to find out Eunuch Hong is actually Ra On! 

Lee Young starts feeling suspicious about Kim Byung's whereabouts and bloody stained clothes in his bedroom. Meanwhile Chief Eunuch Han starts to pursue on Ra On's mother to ask her joining the rebellion gang. Immediately she shot down the idea asking to leave them in peace. Good one, Mom! 

Now Yoon Sung is getting edgy and tailing his grandfather's minions alarming some letter is to be delivered to the palace. Something dangerous and big is going to happen. Several masked men infiltrated the palace grounds (seriously! Now where are the damn royal guards?)  Yoon Sung quickly informs Young that Ra On needs to leave the palace otherwise both will be in danger. Ra On gets her shock of her life with sword pointing to her neck by a bunch of masked men. As the assassins marched towards the Crown Prince's quarters, Yoon Sung slays the masked men on his way of rescue! It's high time for Yoon Sung to kick some bada**! Young has no problem taking down the assassins however one of them aimed the sword straight to him where Yoon Sung caught the blade with his bare hands!

It has come to a point that Yoon Sung emphasizes his friendship with Lee Young even though he belongs to the Kim clan. Unfortunately one of the masked man managed to graze and stab Young from behind. Ra On's tears start to fall seeing how Young start to collapse. Young thinks it was Kim Byung who has betrayed him however as the masked men was collapsed down, it was Kim Byung who came to the rescue. At last, our fears is over since he was still loyal to the Crown Prince. He even apologized for running late to save him.
Young recovers from his injury and re-assures Ra On that they will keep that happiness and no one can take it away from her. 

 

One after another problem follows after the shocking attack in the palace, Ra On visits her mother only to find out her conversation with Dasan Jeong. Ra On's eyes grew big realizing that she is the long lost daughter of the rebellion Hong Kyung Rae! 

I must say the winner of this episode has got to be Yoon Sung. He has proven his friendship and loyalty towards the Crown Prince. With all means he even went against his grandfather's wish and plans. He treasures his friendship with Kim Byung and Lee Young while he pines for Ra On's love.
