A love comedy about a sukeban, Atsuko, and a transfer student, Riri, who thinks she's cute and likes to make her say cute things. In service of the sukeban theme, it's set in the '80s. The writing doesn't particularly seem to be trying to avoid anachronism, but the art style sells it and I think that aspect is the highlight of this title.
