“You can't head back to class... like this.”
Akira Kurokawa, a boy who harbors an inferiority complex toward his perfect twin sister, ends up in the same class as Rise Hotaruda, his sister's friend who likes to teasingly calls him “Little Brother.” Despite Akira being a gloomy loner with little interaction with others, Rise begins to close the distance between them. One lunch break, while he’s eating alone on the stairway leading to the rooftop, she finds him—then suddenly pushes him down. As she licks him all over, saying how much he reminds her of his sister, Akira...?
A bittersweet and indecent moment of youth...
