This wasn't as much of tear jerker for me as 1 litre of tears until the last 2 episodes which were really sad. The plot I guess just seemed lacking -I'm not sure exactly why- but I think it would have benefitted to have more interaction with the friends (also I felt the relationship between the two leads just lacked "chemistry" in most of the drama-like when he told her he loved her it just didn't cut it in my book). Also, this drama in some ways seemed almost too "dark" and in others it was just too light for the content it contained to really shine to its full potential The acting by the main girl was well done in the disease progression, but the male lead at times just didn't cut it half the time -he just seemed too detatched/unsure for the most part yet in certain scenes he really "knocked it out of the ball park". The actors and actresses that played the friends, doctor, and families all did very well. Music was really good for the most part, but some songs were excellent. I don't think I will be rewatching this as it had several issues of various natures, but if you liked 1 litre of tears and are looking for a similar although less heartfelt story you may enjoy this drama.
