Summary:
"Cinderella married the prince. However, she never expected that their eternal love pledge would end after just 10 years. The prince, who had been infatuated with another maiden from the very first sight and made her his queen, even proposed to her.

'You rascal!'

But day by day, Cinderella was wasting away, and there was nothing she could do to help her. Because I was turned into a mouse! Not just any mouse, but the smallest one, at the very bottom of the mouse hierarchy, a field mouse.

'Fairy godmother. I'm just a loathsome mouse, but Cinderella is the one who held me dear. What I wish for is... I hope Cinderella can smile again.'

I thought I was dead, but when I woke up, I had travelled back in time to Cinderella's childhood, when she was oppressed by her stepmother and stepsisters.

'I came on behalf of the Ratton family.'
But what if I wasn't just an ordinary mouse but a member of the Ratton mouse clan? What if my family was desperately looking for me? In that case, Cinderella, let's run away together before the prince comes looking for you with that glass slipper!
