There's not so much "drama" as there are "emotions". The actors were outstanding. No lines from the main character. This was very a unusual movie. It felt like you're watching more then understanding more, if you know what I mean. It's great if you don't like subtitles :P It was nice watching something different then the unusual. The writers did a good job making the feel of the story & setting of the mood, and the actors did wonderful at prompting the affect of emotions.
It was fantastic. This was my VERY first drama I've ever watched. For a beginner, it's really hard to catch the storyline, get all the character's names so you know who's talking about who (& faces), read the subtitles, grasping the emotions & moments given... Man, it was work for me, compared to anime (plus I HATE Romantic >.
