Suzuki Shion is a second-year student who attends Namiki Highschool, and leads a rather average highschool life: her older sister is a teacher in the school, she has a best friend, Akemi, and she has several cute male classmates, none of which she has a particular favoring for, but like most highschool girls, dreams of falling in love. Her hobby is writing songs, but she keeps it secret, having no faith in her small musical skill.
When she was a child, there was a time she had been bullied and a boy had come and saved her, and with a childish heart, promised to marry her. But now it is just a faded memory from childhood with a person who's name she can't even remember, and she thinks it was all just a dream. Pushing back the memory of that first love, she hopes to find a wonderful lover this time.
Then one day in October as she was walking to school, she is stopped by bullies on the way, and is rescued by an unknown boy, who she finds out is Kurosaki Touya, who is just transfering to her school. The event brings back her childhood fantasies, that perhaps they weren't a dream afterall.
Then by chance, one of her songs is discovered by Touya, and she is asked to help with recruiting students to form a school band and compose for them, with Touya as the vocals. Feeling flattered and compelled, she agrees. Will she find love with one of the band members along the way?
