Konno Hikaru is a high school girl who took over from her late father as the second generation handyman. At the homes of clients, she is asked to provide services beyond the title of "handyman." She works diligently in her uniform, but then succumbs to the man's desires and lewdly lifts her skirt. The ignorance and curiosity of youth lures her into a dangerous world of pleasure. She accepts creampies as part of her job, and is repeatedly penetrated. This is the turbulent work diary of a high school girl in a uniform, where her sense of responsibility as a handyman intersects with her awakening as a woman.
