this drama is perfect ! how can a drama like this have a negative aspect when it has such a talented and hardworking cast ?? (lee jehoon, pyo yejin and esom THEY ARE AMAZING). the scenes of this drama can be fun to watch but some of those scenes are full of action and will make you feel tense for a really long time, but it's worthy. the ost is amazing specially silence by yb. i hope this drama gets more recognition and viewers, i need more kim doki lovers and ahn goeun defenders. don't die, get revenge, we'll do it for you.
