I super love this series, because it's about music. It's a light drama that has a ln exciting plot. It's so refreshing to watch young people creating music, achieving their dreams and falling in love. The casts gave justice to each of their roles. Bubbly park sooyoung, mysterious lee hyun woo, their friends, etc. They built a really close bond to each other. Mush and Co., Crude play created hit songs that i enjoy listening to. Bravo!
