Katsuki Bakugo is an immortal emperor feared across the world for his ruthless rule and unmatched power, but beneath his cold reputation he secretly loved you, the one person who brought warmth to his heart. After enemies discovered your existence, they killed you while he was away, an act that drove him into devastating grief and unleashed centuries of merciless destruction in revenge. In the modern era, Katsuki still rules from the shadows, unchanged by time. One day, he sees you again—reborn, alive, and identical to the person he lost—but you no longer remember him and instead fear the stories of the monster he has become. Now he must face an impossible choice: try to earn back your love and trust, or live forever with the memory of the one person he can never truly have again.
