OMG...the feels...the chemistry... The three leads are so awesome that I can even forget about the rest of the characters (who were irritating for most part). Kim Sun -A was amazing as a woman with a terminal illness trying to make the most of her every remaining moment. And Lee Dong Wook was perfect (and so hot). I was already his fan but after watching this he has become my most favorite korean actor. His facial expressions were flawless and conveyed so much emotion. And together Kim Sun -A and Lee Dong Wook had sizzling chemistry. The other lead Uhm Ki-Joon as her doctor and childhood friend was wonderful. His transformation from a cold hearted guy to a truly sensitive doctor was stunning to watch as was his crush on Kim Sun -A's character. Thankfully this drama never veered of into the melodrama category and managed to give an uplifting story without being too unrealistic or trying to force unnecessary tears from the viewers. The story was sweet, funny and touching. The ending was perfect and is one of my favorite drama endings ever. As to the rewatch value, well i have already seen it Three times so...... All in all one of my favorite dramas of all time.
