Four years after a messy, emotionally volatile breakup, Katsuki Bakugo and Y/n have built completely separate lives—he buried his past in silence, while she rose to fame as Osaka’s most celebrated singer, her voice carrying everything she once couldn’t say out loud. Neither of them ever spoke about what happened between them, and Katsuki made sure no one knew she had ever been part of his life. But when Katsuki is reluctantly dragged to one of her sold-out concerts by his friends, the past he thought he left behind resurfaces under stage lights and screaming crowds. Seeing Y/n again—no longer the person he once knew, but someone transformed by time, pain, and success—forces both of them to confront what was never truly resolved.
