This drama damn near made me cry and I rarely cry while watching tv shows. The cliffhangers in this one will keep torturing you till you click on the next episode. I loved everything about this drama; the story, the characters, the acting, the suspense, the subject matter, and the ending. Teacher Kim is easily one of the best villains in Kdrama history. I thoroughly enjoyed her character and I want more of that in every drama villain. The variety of expressions, the gut-wrenching backstory and the meaning behind her actions... it was all superb.

If I must point out, there are only two things I did not particularly enjoy: The one-dimensionality of Woo Joo's character, and the not very enjoyable humor coming out of Jin Jin Hee's family, it got a little boring after a while and I found myself skipping her scenes entirely.

You must watch this drama, if only for the villain, and that is reason enough I assure you.
