Cinderella married the prince. But she never imagined that their vow of eternal love would last... only 10 years! All because the prince fell in love at first sight with another noble lady, kept her as a mistress, and even proposed to her. "That bastard!" But there was nothing I could do for Cinderella, who grew more lifeless with each passing day. Because I was... "Squeak!" A mouse! And not just any mouse—the smallest, weakest field mouse at the very bottom of the hierarchy, constantly being stepped on. "Dear Fairy Godmother, I may be nothing more than a repulsive rodent, but Cinderella was kind enough to care for someone like me. All I wish for... is for her to smile again." I thought I had died. But when I opened my eyes, time had turned back! To Cinderella's childhood, when she was still being abused by her stepmother and stepsisters. "I've come on behalf of the Ratson family." Wait—I'm not just an ordinary mouse, but a beastkin from the noble Field Mouse clan? And my family has been desperately searching for me? In that case... Cinderella, run away with me! Before that stupid prince comes around with his glass slipper, I'm taking you away myself!
