lol! I play violin, and when I saw him "playing" I had to rewind a few times. >_< Even if you are not a violinist, you can definitely tell that he is not playing. Other than that, this is an okay drama.
They made the trailer well. I can already tell, it will have a LOT of cliches, but... it looks GOOD. Plus I love Rosy she is just a bundle of joy and adorableness.
