Yoi discovers the idol she devotes herself to, Hikaru, is actually Akari, the black-haired, glasses-wearing boy sitting next to her, after Akari asks her to teach him how to study. From then on, they meet regularly after school, just the two of them. Akari usually has no aura of an idol, but the "real" expression she shows in a moment is very cute... Little by little, Yoi finds herself drawn not to the idol Hikaru, but to the high school boy Akari. A secret after-school lesson with her "favorite" idol! A royal roadside love comedy that will keep you on the edge of your seat!
