You're Vulnerable and Cute

Nagisa Asaka is only a first-year student, yet she is already the volleyball club’s ace. Gifted in both academics and athletics—and adored by boys and girls alike—she receives confessions on a regular basis. But since she has never fallen for anyone herself, she has turned them all down. Troubled by the thought that she might not experience love the way everyone else does, Nagisa one day meets Aoi Tobari—a delicate-looking boy with an almost girlish appearance. The instant she lays eyes on him, she is overcome by a desire unlike anything she has ever felt before: “I just want to mess with someone this cute and helpless.” Thus begins a pure first love—born from the most intense, twisted, and downright awful feelings imaginable!
