Story- I gave it a perfect score mainly because it was really Ozmmm, Awesome, Fantastic, Masterpiece. Acting/Cast- Nothing's wrong with the casting, I guess? Music- I don't really care about the music of any drama, but I guess the negative 1 would be mainly because the song was sad? (I'm so unreasonable, sorry =D) Rewatch Value- Once you watch it, you'll definitely want to to watch it all over again, I mean, it's so great that's what I felt. Overall- 10, Masterpiece. Hmm, When I was watching this, I was like "I wanna finish this ASAP". It makes you think what would happen next and makes you wanna finish it all in an instant. The twists were great as well as the cutting of scenes per episodes.
