The story follows Aya, a modern and lively high school student, who falls in love with an employee at a local CD store. This employee has an air of mystery, always dresses stylishly, and has excellent taste in music. However, she doesn't know that this supposed man is actually her classmate, Mitsuki! Mitsuki is usually reserved and withdrawn, but because her seat is right next to Aya's, she can't help but be very cautious with her crush.

The revelation of the truth seems impossible, but perhaps getting closer to Aya might not be so bad...
