This drama is the best drama I've ever seen. at the end of this, I had literally cried a liter of tears.. its such a moving and beautiful story, and it makes it even more powerful to know that its based on a real life story.! one day I would love to watch this again, but I remember being half depressed a week after finishing this drama, that's how much of an impact this story left on me. this is a must see for every one. it will leave you with the ability to feel a great deal of empathy.
