I have seldom watched a drama where I've been this attached to the characters and story. From the acting to the storyline to the characters to the emotions to the suspense and thrill, everything is so good and so well done. The twists and turn throughout the whole show had me on the edge of my seat. The main lead's acting is amazing, just his eyes hols so much emotion. I would recommend this drama to everyone (The number of tears I've shed for this show is embarrassing, especially in episodes 13 and 14).
