STORY: Okay i really love these kind of dramas with such amazing cast! I for YEARS tried to find some drama with action/spy AND powerful romance! The romance is very innocent, passionate and deep so if u want to see very deep emotional moments go for it! The action scenes were done also very good and kept the drama in a good flow. For me i did marathon and i NEVER found any moment boring. I know everyone has different opinion but this was....really wonderful. After year and half i finally watched drama guys and i enjoyed it so so much! The plot is very interesting and i never saw such plot so this was something very new and fresh! Keeps ur mind busy and trust me...you will lose your sleep XD ACTING: Okay I watched dramas with JCHW before and i knew he had talent but this like...smacked me straight in head and woke me up! I can tell he is a top actor and i don't care what others say. He seemed like he was really the character he was playing. From the first ep his face started to change with emotions..Nothing was too much and nothing was missing. It was perfect! Main lead girl is also great actor and i know her and i can tell this is her best role. I love that in this drama she is also the brave girl who will stand in front and fight for justice ^^ MUSIC: Honestly the main song '' Eternal Love'' is downloaded on my phone and i listen to it all over again. It's too good. And did u read the lyrics? No? Okay than go and do it! It's so sweet and so real and it fits the main couple! REWATCH VALUE : To tell you the truth i started to watch it all over again right now XD It's too good to just watch it once...So right now i'm going at it once again! ^^ This drama is filled with emotions so enjoy it and give it a try i can tell u..that you WON'T regret it :)
