Adaptation

manga

High schooler Aoto Ichigaya’s light novels of forbidden love aren’t exactly flying off the shelves—but he’s got bigger problems right now. His cute-but-psycho stepsister Shizuku has decided the way to his heart is through hypnosis…which doesn’t actually work, but Aoto isn’t about to let her know that. Aoto’s childhood friend, Rinko, might be his only hope of rescue—if he even needs rescuing at all. When your stepsister wants to kiss you and kill you, there’s just no way for a guy to win! *Source: Mangamo*
