Tomoharu Okabe, an inexperienced and earnest young manga artist, is hired as the illustrator for a popular erotic novelist, Tougo Tsubaki. Despite Okabe's initial anxiety and lack of confidence, Tsubaki insists he needs the work, claiming Okabe lacks the necessary sensuality to properly depict the scenes. Under the pretense of professional coaching, Tsubaki begins a regimen of explicit instruction, using his own小说的 text as a script to guide Okabe through a series of sexual encounters. The relationship develops from a purely transactional dynamic into a consuming romantic and physical entanglement. Okabe remains a cautious and naive counterpart, while Tsubaki, a seasoned hedonist, gradually moves from treating him as a fleeting amusement to developing genuine emotional attachment. Their bond is tested by outside figures, including Tsubaki's casual lover, an AV actor named Toranosuke, who threatens the newfound exclusivity of the relationship. The main narrative arc charts their evolution from a strictly professional arrangement through a period of purely physical connection into a deeper and committed partnership, ultimately leading to them living together. The collected volume also includes side stories exploring additional pairings, such as a relationship between a young kimono shop heir and a traditional dance instructor.
