Ichirou Kuga has more on his plate than just his pen. Since his father's recent death, he has been the sole provider for his younger siblings, Machi and Fumio, while also taking on landlord duties. All of this comes on top of managing his shoujo manga career, where he has only just barely achieved recent success despite constant deadlines and a lack of assistants. Yet Ichirou remains determined to push through for his siblings' future, until one day his editor calls him with some promising news. Rushing outside to find his new assistant, Ichirou meets 19-year-old Shiori Goshiki, who quickly reveals herself to be a talented young woman through some swift inking. As this is her very first job in the industry and she only recently got into manga, Shiori seems out of this world—in more ways than one, as Ichirou discovers after a mid-work nap when he dazedly mistakes a pointy pen for something sticking out of her body and reaches out to save her. But when she wakes up and immediately tells him that touching her stinger essentially renders them betrothed, Ichirou doesn't know what to think!
