First of all let`s talk about the story, the actors/actresses and the music: +++++++Simple Summary, Deep Connections++++++ We all know that dramatic structure consists of exposition, rising action, climax, falling action, and denouement/resolution.... but for me each episode was a climax. You know what I mean? Every episode that I watched, i felt the tension, the hatred, the thrill, the excitement, the depression, the frustration,the sadness, the happiness, and the enjoyment, in short super mixed emotion. The suspenseful event happened unpredictably and unexpectedly. oohhh yyeeeaaaahhhh!, I'm hooked. The first thing that come through my mind "oh man, let me see the next episode if my guess was wrong!" then after a week " oh yeah I'm very right, all my guesses were wrong". So I'm thinking behind with confusions dragging my self along with the story till the last episode knowing that i will never guess it right. There are many special things that i liked about this drama but I could not figure out what are those...just see for yourself! But I am positive that every time I watched this drama I unconsciously following/copying the facial expressions of the characters. Gosh, be aware,ok? others can see you. for example: Whenever I see _******_ angry expression, I grind my teeth, smirk or grin unknowingly that I followed his facial gestures too. Every time _******_ is having a bad time, I frowned or grimaced because I just saw her like that, I felt i was the one who is in her place. That make sense, aye? The portrayal of the characters is felt and not over used in the story. They matured as the story went through (both villain and protagonists). The main characters were kinda extrovert type of person. Limited thoughts and conversations though their dialogues and lines meant a lot beyond simplicity. I heard intense music when tensions between characters took place. It might be repetitive but it still sounded so suspenseful that I never get irritated after so many times. There was also the song of the main character and that song was used wisely (they played it when KM and EG is involved). So this drama got 10 for me because they deserved it. Very well executed as mentioned from other post. lol! I liked the fact that the last 3-4 minutes or so of each drama was purposely shown accordingly. When new episode aired, sudden twists occurred. Those 3-4 minutes from the previous episode would showed up again with added scenes in-between that makes the story more interesting. Unlike any other dramas that just continues where it left off. First Impression Lasts... go for Episode 1 If you were not impressed enough... go for Episode 2 If you are still confused... go for Episode 3 You are not convinced yet?... try Episode 4 Oh come on, try a little harder... watch Episode 5-10 You want more?!...time to follow your instinct. Not enough effort to watch?!... okay then, skip everything then go for the last episode (ep 20)*if ever the last episode impressed you, you might wanna consider the first episode instead. I already watched this once so it is enough because i won't be thrilled as much as I was before. Simple truth: I knew what would happen next, same story line.
