"Fly Again" depicts the growth stories of boys and girls in an art high school who fly towards their dreams. The K-POP club "Billance" moves towards the dream stage despite all kinds of hardships. The blood, sweat and tears of the children who turned the world upside down have attracted the audience to join the show. K-POP is gaining popularity around the world, and the birth of a new K-POP musical TV series that uses music and idols as materials to attract attention and ears is expected.
