"You've turned me into quite the pervert!" Sugawa, the cool and seemingly composed popular boy, is in a passionate relationship with Murasaki, a candid and playful troublemaker. They make out around campus without hesitation, and their chemistry is obvious to anyone watching. There's just one problem―Sugawa never takes things all the way. Whenever their kisses start to deepen and Murasaki tries to lead him toward something more intimate, Sugawa always pulls back with some excuse. The constant teasing without release drives Murasaki crazy with frustration. Determined to break through Sugawa's reservations, Murasaki launches a full-on seduction operation―tempting him, provoking him, getting handsy―yet nothing works. Finally pushed to his limit, Murasaki snaps and threatens to break up. That's when Sugawa suddenly grabs him, kisses him hungrily, and growls something that turns Murasaki's world upside down. "I've been touching myself to you every single day," he confesses. Could it be that the stoic, unshakable Sugawa is actually a hopelessly depraved pervert completely obsessed with him?!
