The first ten episodes are interesting and engaging. Love how they put more backstory about a run away renowned badminton athlete which hinder her to play badminton. But after the 10 episodes, it got draggy. The conflict between Taeyang and Junyoung could be resolved in earlier episode without making it repetitive. I was excited to see Taeyang play again and her playing without feeling guilty but instead they give us more drama and less badminton scenes. The only thing that keeps me going is the chemistry between the leads and the other players. Park Juhyun really gives an amazing potrayal as a used to be famous badminton player who now feels guilty to even to play because the conflict she has with her best friend and how she's having this inner problem within herself because her mother left her and she got adopted, and she feels that her adopted parents will abandon her if she fails to play badminton. Chae Jeonghyeop also gives a neat potrayal as Park Taejun, a skilled badminton player living under the shadow of his sister success. I hate how his parents, especially his mother, treats him. He and Taeyang find comfort and love on each other. Both Juhyung and Jeonghyeop have good chemistry with each other. On the other hand, I don't really feel the chemistry between Yook Junghwan and Lee Yoomin. It's too bad that I don't feel the excitement to watch after the 10th episode, really wish it could be better.
