The first 6 episodes are slow and a little boring and the sparkle between the main actors is very little, yet there is something special about it, I mean, mostly in romantic dramas love is so perfect it seems out of this world and unreal, but in 'Heartstrings' it's more simple. In this world there are guys like Lee Shin, in relationships with that kind it's not so emotional and full with sweet stuff. Music is awesome, but this drama is far from being perfect, I wouldn't watch it twice, because the story's very ordinary.
