Yukimura Aine is a seventeen-year-old high school student who writes sensual song lyrics and hopes to become a songwriter.

It is driven by Sakuya Ookochi, lead singer of the hard rock band Lucifer, which is known for its sensual lyrics.

Seeing her talent, and wanting to win the girl, Sakuya campaigns for Aine to become the band's official lyricist.

Although Sakuya is not subtle by nature, he attempts to express his feelings for her by writing a ballad called "Little Bird" or "Love Melody", but she continues to misunderstand.

As the series progresses, Aine finds herself the frequent target of Sakuya's enemies, including rival bands and obsessed fans.

Ralph Grazer, Sakuya's older half-brother, is an American media mogul who heads a business empire in the United States and is branching into Asian markets.

Sakuya travels to America to learn the family business, which gives him the knowledge and power to take Ralph's position as head of the media corporation.

At first, Hitoshi thinks Aine is nothing more than an outspoken groupie, with no place on band premises or in Sakuya's life.

A guilt-ridden Hitoshi finds Aine and takes her to his home to try to comfort her, helping her avoid Sakuya out of shame, self-loathing, and fear of being rejected.

Aine snaps out of her depression and begins to heal emotionally, even confronting and threatening Yoshioka to never bother Aucifer ever again.

Takayama's death in a car accident traumatizes and pushes Sakuya to rejoin the band and sign the contract.
