The story surrounds the aspiring and energetic singer Shuichi Shindou, with his band, Bad Luck (formed with his best friend Hiro), wants to become Japan's next big thing, like his famous idol Ryuuichi Sakuma, lead singer of the disbanded legendary group Nittle Grasper. One evening, Shuichi is writing lyrics for a song when his paper is blown away by the wind and picked up by a tall blond man. The man dismisses Shuichi's hard work, which hurts Shuichi deeply, although he is intrigued by the stranger. This will be their first, but not last, encounter, as Shuichi will become fascinated by the stranger, who turns out to be a famous romance novelist, Eiri Yuki (Uesugi).

The story expands to include the beginnings of Bad Luck and their rise to fame, as well as their rivalry with the band ASK; the reformation of Shuichi's idol's band, Nittle Grasper; a long suffering fiancée of Eiri's who wants to finally marry him and serves as an enemy then an ally for Shuichi; the public scandal surrounding Eiri's and Shuichi's relationship; attempts by Eiri's inner circle to keep Shuichi away from Eiri in "Eiri's best interests"; and the secret of Eiri's painful past that he has trouble remembering and which is keeping him from giving in to his feelings for Shuichi.
