These people have been living unhappy lives because they've never been able to do what they want.
Ga Yeon's smart, but wants to become a singer. However, the Korean educational system strongly enforces studying to students without considering the goals and dreams of the student. She's been forced to live a life of suppression.
Jae Hee is a piano player, but he's been living in constant delusion of his life. He has mental problems and cannot distinguish reality from a dream.
Dong Woo and Min Seo are a couple who are talented musicians but cannot make music they wish to make because of the current situation of the Korean music industry.
Hyuk's a very good guitar player, but is forced to be in an idol band, rather than what he really wants to be.
The 5 come together to make a band of their own.
(The story conveys clearly and straightforward the psychological changes and developments of each characters without being dull. It pulls you in and dips your skin into their world, reflecting our reality into lines and colors magnificently.)
