I'm not even going to say too much about this drama, it is simply beautiful and demands to be watched and appreciated.
This drama is about the redemptive power of simple gratitude, how the words 'thank you' have the ability to change your outlook and ultimately your life's path, no matter what your circumstances are.

The cast as a whole is superb, there are no stars here, just a well rounded ensemble of gifted storytellers, such is the power of this story that stars like Gong Hyo Jin and Jang Hyuk, although they delivered wonderful performances, they still managed to blend in with the other relatively unknown cast seamlessly.

I do. however have to give special mention to Seo Shin Ae and Shin Goo; Seo Shin Ae's precocious portrayal of Bom is stellar and amazing, she elicited tears and laughter in equal measure and was an absolute joy to watch.
Shin Goo's portrayal of Mr Lee or grandfather was awe inspiring, he injected such pathos into his character that I was completely engaged whenever he was on screen.

This drama is amazing and is definitely worth watching, you will not regret it. It reminds me of why I watch Kdramas in the first place, it is so full of HEART.

I give it 10 out of 10 in all categories. SIMPLY SPLENDID!!!!!
