I'll not write a consistent summary, this can be found on Asianwiki. I'll write why I rated 10, why I like this, what I found great in the filming technique and acting. There are at least three main characters: Ji Hoon who wants to save his mother by a deadly liver disease; Hye-Soo a single mother who want to be a transplant donor, she herself find to be very ill; Hye-Soo's little daughter Eun-Sung who is truly adorable at only seven years old .
First, I like the pace of film, well balanced. Secondly, in this drama are a few scenes filmed from many angles, I like enormous that is not a lazy filming technique. And so many well framed scenes: bedtime late conversation between mother and daughter, some wonderful hand grips, a few nice hugs, the harsh conversations of the main characters with Ji-Hoon's father, an amazing godfather, literally. Thirdly and the most importance for me is Eun-Sung's acting (actress Shin Rin-Ah): I'm in awe how the filming team managed a child, clever indeed, to perform a lot of brilliant scenes, to sustain long dialogues. She is the cherry on the cake, without her all drama is void. I emphasize again, I'm enchanted how the crew ,director, writer, managed to highlight the girl. I feel and that good chemistry between mother and girl; praises for this to actress Uee.
