This drama is pretty underrated. Also it is a feel good drama. If at the end of the hard day you want to watch something to pep you up this is a drama for you! This is a multi character drama of the k pop music band. I loved the story and cute moments in the story i still go back times to watch some of the scenes. I liked the music too in this. Story is about a band who the band leader who is so perfectionist that he fakes some of the aspect of the band, it is about the members who wants to work hard and prove them selves and how competitive the world out there is. It has a love triangle of kids and adults. It has many funny moments and heart touching moments. I loved how kang and yoo soo rim's relationship develops. I liked acting of Lee hyun woo in this and after this i watched couple of his drama which i liked. Choi jin hyuk is competitive but towards the end he realizes the true sense of music and protects that essence of music. I think i liked this drama because i like music. It's a journey of many character and how they fail or successes in this world of music and their interpersonal relationship with each other. It's cute !
