Summary
Official Details
High school student Ryouta leads an ordinary life, except for one thing: his older sister is an aspiring manga artist. At 21, she has dedicated herself to her craft, but her focus has left her with no romantic experience. When she lands her first job, it's to create an erotic manga, and she's unsure of how to approach the subject matter. Desperate for guidance, she enlists Ryouta's help as a reference model, tasking him with reenacting intimate scenes to help her accurately depict them in her work. While Ryouta's sister, Mana, views these interactions as purely professional, she fails to notice the effect they have on her brother, who becomes increasingly flustered with each "live performance."
