I watched this because I had just finished Extraordinary Attorney Woo and I wanted to see Park Eun Bin outside of that extreme autistic character. And she does not disappoint. If I had not known the characters Woo and Seo were played by the same actor I would not have realized it. It is a remarkable talent that can take the audience so deeply into the character as to not see the actor. There are too many famous actors that overwhelm the character they're playing so that the audience only sees the actor.

The music and performances are well worth the time. The story and plotting are at times fragile meaning that characters' twists and motivations were not always believable and relatable. However, the acting and music carry the flow and engage the viewer. I found the first few episodes not as engaging as the later ones. At times the plot twists seemed overly complicated and manipulative. For example early on I became aware the writer wants to play with the audience as to which brother is KiHo. Once aware of that manipulation, instead of the story flowing naturally the audience becomes too self conscious that the clues obviously dropped are likely meant to be misleading.

I found the positives more than made up for the few flaws and kept me engaged through to a satisfying conclusion.
