Just completed watching this series a second time. Really enjoyed the music and the cute storyline. The music is the BEST and it truly brings out the story more!!!! It is just hard to believe that no one would realize that Park Shin Hye, who is playing as her twin brother, couldn't be recognized as a girl. It's her innocent demeanor and expression that makes that series come alive. It is so sad for her to find out that her mother passed away and that her unreachable star is so distant. The ending was definitely the BEST for me but if I were to choose between this series and Operation Proposal's ending. I would have to choose Operation Proposal but it is definitely still worth watching.
