There are a lot of things that make a drama worth watching. But the one thing that makes a drama 'unforgettable' is the appropriate use of it's theme and maintaining the moral of the story throughout. This drama picked up a very controversial topic in medicine and law and handled it really well. It gave no definite answers to Euthanasia but just like the endless debate, left no side as the bad guy and no side as the good guy.

Instead of focusing on pain leading to 'death' as an abrupt end of life, this drama focused on 'living' till the very end. It gave a very memorable perspective to death and life. It may not be the best medical drama, but this drama was much more. It left valuable lessons and worth watching perspectives behind and that is as important sometimes.

The acting was quite obviously outstanding. Nothing less to be expected from Ji Sung. Doubt any other actor could have portrayed the different emotions this drama and story required. He was as usual phenomenal. The other actors were brilliant as well, especially Lee Seyoung who is most definitely a very promising actress.

The soundtrack was brilliant and fitting in every scenario. It was both melancholic and hopeful, happy and sad. Just perfect. The romance was handled very well. Not the typical romance drama types but rather a mature romance. Practical, deep and beautiful.

This drama did justice to all the tags and to it's viewers in my opinion and is definitely worth investing your time in. Also i mean, it's Ji Sung! Come on! Haha.
