Boku no Risou no Isekai Seikatsu: Tensei shitara Kemomimi Musume darake no Sekai de Harem ni

For forty years, a man endured a grueling life as an overworked, exploited salaryman who never experienced romance or marriage. Despite his deep love for cute girls, he remained entirely alone until the exhaustion of yet another sleepless night at the office finally claimed his consciousness. When he opens his eyes again, his bleak reality has been replaced by something extraordinary: he has been reborn as Norn, a young kemonomimi man in a vibrant fantasy world where animal-eared girls vastly outnumber men. In this new life, Norn is immediately introduced to Mysia, his adorable and devoted fiancée. However, she is only the beginning. Before long, a steady stream of beautiful, affectionate beast-girls enters his life, each presenting herself as a potential bride and pushing him toward the ultimate harem he once could only dream of. Yet, beneath the idyllic surface of this female-dominated paradise lies a profound and hidden secret about the true nature of this world—one that threatens to change everything Norn believes about his ideal second chance at life.
