It might come a time where you realise you wasted all of your time watching a seriously pointless series. I started this series initially cuz of Lee Long who had great acting abilities in I hear your voice. The story started good and was packed with action and suspense. But, I don't know what exactly they were trying to do when they made the story so freaking ambiguous, with so many holes that you couln't even sympathize with the characters. I wasted the first 10 episodes trying to understand where the heck all this was going... I really hoped the writers were really trolling me after one point. I rarely drop a series but I didn't manage to finish the last 2 episodes, I skipped to the end. To realise how stupid I was for ever continuing for so long trying to find the point. NONE , don't waste your time. The only thing that can be mentioned is the acting abilities of the 2 male leads, which towards the end didnt even realise just why the heck they were even acting anymore. Oh, and music was good. I wish I could put the story minus 10 but it doesnt let me ;_; However, I want to say that this drama did give me a lesson: Always read the reviews before starting something. The most satisfactory thing for me would be if all 4 main characters dropped dead in the end and made it a tragedy. It would give me some compensation for all the misery this show has put me to while watching it.
