The story was light at the start, well combining a few confusing flashbacks and so, doesn't really hurt.

This drama will bring you to what works behind the curtains of musicians and orchestra. That makes me stay and had the interest to understand a few things with how music works to a few. The story went too deep to the unknown murder and so, it was thrilling and frustrating to watch.

The lead roles gives justice to their characters, especially, Kim Sejeong... I think she was always too prepared to cry that her real bubbly self was drag down together with the whole story. But I was amazed that Woo Jin and Kim Sejeong has very strong chemistry that you just wanna watch them. That made me stay and watch this drama. I think more than anything, you will see a different side of Kim Sejeong's acting... Immersed and justified.
