It's been thousands, if not millions of resets since Frisk first fell. Countless times did they save everyone, countless times did they kill everyone. Countless times did they give Asriel a second chance and countless times did they condemn him back into his own little hell, taking away everything he build for himself. Nothing was permanent and every day could yet again mark another beginning of the same old journey. In one last, desperate attempt to take back the life he was never meant to live, Asriel starts to take matters into his own hands. He would find his happy life, he would find permanence, he would find a way to stop the resets. Even if it meant sacrifice, even if it meant rewriting the universe.
