Makoto Ninomiya and Akira Kuji are childhood friends who grew up next door to each other and were like family. Makoto has a cute face and was always made to dress up as a girl by her mother and sister since she was little, while Akira is tall and has a boyish look, so when they go out together, they are often mistaken for a couple with the opposite gender. Makoto has actually had feelings for Akira for many years and wants to take a step beyond just being childhood friends, but Akira, who has no idea about her feelings, seems to be satisfied with their current relationship. Meanwhile, Makoto accompanies Akira to a group date dressed as a girl, at his request, where she unexpectedly meets a rival (!?) - Will the two, who care for each other and are more than best friends but not quite lovers, be able to "escape from childhood friends"!?
