nice director ,nice story, nice acting ,nice scriptwriter,the drama is interesting and was already full of mystery from the start,but all is clear at the end of drama ,when i completed the drama ,i listen the novel a little in YT and i think the drama version is more good ,some story is different from the novel but the plots is better like that, the heartache feeling when finished the drama, when we found a good drama , i save 53 54 episode end when i rewatch it ,the feeling have not faded, especially when the ost is playing (´⊙ω⊙`)(´⊙ω⊙`)(´⊙ω⊙`)
