I honestly can't think of any way they could improve this drama. The story was heartwarming and creative with a little bit of suspense mixed in. It's both funny and sad. All the actors did a phenomenal job. The 6 year old "twins" were adorable and talented.

I enjoyed this drama from the first episode and was a complete fan by the 6th or 7th. This is a must watch for people who enjoy family dramas. If you are more interested in romance and idols, then you may not enjoy it.
