Let me start by saying Rain and L are the standout actors in this drama. In fact all of the actors do a decent job...especially some of the side characters. The fault seems to be in the writing. The concept is interesting. A man who falls in love with the sister of his deceased love. And really, up to about episode 15 I went along with it. But in Episode 15 and continuing into 16, I just wanted to smack the female lead. Her decisions literally made no logical sense at all and she never really explains herself...but in the end all is forgiven? So strange. Just so strange.

The music is fine, but since the show is about music I really hoped there would be at least one really amazing song, but there isn't. Though the song written for "all the mothers" is very good.

I don't think I would rewatch this just because the end is so frustrating. And when it finally comes together, it immediately ends leaving you thinking, "What?" I mean there is a happy ending, but the female lead's actions are just so strange that it makes the ending feel off.

The drama is worth watching at least up to Episode 15, but 15 and 16 are just rough to watch.
