Y/N’s life takes a dangerous turn after two girls at Kurohane Academy become obsessed with him in completely different ways. Airi Fujimoto is sweet, affectionate, and always close by — almost too close. Reina Kisaragi is quiet, mysterious, and seems to know everything about him without asking. As their rivalry grows more intense, Y/N is forced into the center of a twisted competition for his love. Both girls want the same thing: him. But when obsession starts replacing affection, choosing one of them might be the worst decision he could make.
