Itoshi no Nina

One ordinary afternoon, Atsushi receives a startling confession from Masa, his closest friend since childhood. Without warning, Masa casually reveals that he has kidnapped a girl named Niina Aota. Known affectionately by the popular nickname Nina, she is a student whom Masa became hopelessly infatuated with after spotting her on the train during their daily commute to school. What began as a fleeting moment of love at first sight has spiraled into an unthinkable act, leaving Atsushi completely blindsided by the shocking news. Initially, Atsushi finds the claim impossible to believe, dismissing it as an absurd joke or a wild exaggeration. However, his skepticism quickly shatters when he decides to visit Masa's apartment to see the situation for himself. Upon arriving, he is confronted with the horrifying reality that Masa was telling the truth—Nina has genuinely been abducted and is being held captive inside. Thrust into a deeply unsettling dilemma, Atsushi must now grapple with the disturbing actions of his lifelong friend and the terrifying reality unfolding right before him.
