Song Of The Cloud구름의 노래 (Korean - gooreum-eh noreh); Песента на облака (Bulgarian)

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. Webtoon from Naver
