気になってる人が男じゃなかった

Aya Oosawa has a crush on a sharp-dressed, black-clad employee at her favorite CD shop, someone whose taste in music she can't stop thinking about. What Aya doesn't know is that her quiet, aloof classmate Mitsuki Koga is that same employee out of her school uniform. Told largely from Mitsuki's side, the story follows her keeping the secret as Aya's crush closes in on the truth. The anime adapts the ongoing manga of the same name.
