I am BIG fan of my sweetheart Kang Dong Won and i will support him in anything he is but why he always breaks my heart?! Story: The plot is great and it shows the people that there are such horrible cases as the sickness the main boy had. Our Dong Won played amazing father and he was simply...amazing. I think every kid should have such amazing father as he was. The emotion he showed me..i just couldn't watch it without any tears. The story whole is so beautiful that i have no words for it. Acting: Great. All actors did amazing job. Rewatch value: Since first time i didn't rewatch it because i don't want to cry but it's too beautiful so i will rewatch it rght now :)
