Its my first time writing a review for a drama but this drama was super amazing I cant help myself but praise it this drama is a masterpiece its super awesome It was a rollercoaster ride right from the start to the end which I really enjoyed... It has a gripping plot, writers did a brilliant job how the past and present time story is intertwined is just great, there is attention to details carefully written, had lots of turns and twists, cliff hangers which were super amazing, unpredictable, kept u thinking on the edge of your seat what will happen next yet u would fail to do so I felt like I was going thru the journey together with Sun Woo every time I was so absorbed into the story that when something worst happened it freaked me out as well cried together with Sun Woo and became relieved and happy whenever something got resolved... I couldn't help myself from pressing the button for next episode as I was too curious about whats gonna happen next how would things turn out to be what would be the effects of the actions taken by Sun Woo... I Loved Sun Woo's character he was charismatic, intelligent, smart and the friend Young Hoon's character as well those two were my fav characters I loved the bonding between Sun Woo and Young Hoon he was a great friend for Sun Woo always besides him Sun Woo was really lucky to have such a friend... also loved Sun Woo's relationship with director Chul Min... all the actors did a superb job they played their roles perfectly Lee Jin Wook was superb as Sun Woo perfect portrayal this was the second drama of Lee Jin Wook that I watched he's really good.. also the actor playing his friend Young Hoon did a great job their younger counter parts acted out there roles nicely and director Chul Min did a good job as well... There was romance as well great chemistry between leads though that wasn't the main focus of the drama but it had a good balance perfect mix... even though I loved the romance between leads but for me the friendship took the center stage in the drama. one more thing I totally loved the expressions/ reactions of Young Hoon whenever he realized something changed, and about Choi Jin Cheol's OMG I found his expressions/ reactions somewhat funny lol haha I totally LOVED the drama, great story superbly told & portrayed, highly recommended to anyone who hasnt seen it yet!!! if you are thinking of watching it go ahead its one gem of a drama...
