The Girl He Was Interested In, Wasn't A Girl At All

Pure Vanilla, a gyaru high school student, frequents a small record store and develops a crush on the clerk, who has dark blue hair and wears a hoodie and a face mask. There's one problem- as the title implies, the clerk is actually his nerdy male classmate Shadow Milk. How will Pure Vanilla react when he learns his crush is not actually a girl?
