Oh My God, I am speechless, this series made me hooked from the first episode. The story is brilliant and unexpected. I won't even mention on how handsome Ji Chang Wook is, but the acting is superb, the action is also good! This series is really one of a kind, comparable with Signal. I don't know why i only watch it now.. haha silly me. Luckily i decided to watch this, coz i read the rating is not good so i judge it, but now i watch it and omg, i dunno what's the heck is wrong with the rating? The story is good! I laughed, i cried, i worried, etc. It has a good plot, haiz! I am gonna miss this drama! I have binge watched it for two days hahaha, I am gonna watch it again, yes! it's that good! Very recommended! I LOVE ALL THE ACTORS HERE! They have their own story and backgrounds, THE MOST IMPORTANT THING IS THERE IS NO STUPID FLASHBACKS hahaha! I just hate flashbacks just to fill airtime, but this one doesn't have it and I LIKE IT! Yes, i am gonna edit my other drama's review coz this one is perfect and not comparable to other drama! Thank you healer, u have kept me entertained!! PERFECT SCORE 100/100!!!
