Yuki believed she was living a happy life with her husband, Kazuma, and their daughter, Aya.
However, everything began to fall apart once it was decided that they would live with her in-laws.
From then on, Yuki was treated like a servant, forced to handle all the housework and caregiving every single day.

Her bond with Aya was torn apart, her husband cheated on her, and eventually discarded her like trash.
Years later, when mother and daughter finally reunite, Yuki is on the brink of death.

“Mom, don’t leave me! If only we could start over just once more—!”

At the very moment Yuki dies, the two of them leap back in time together.
To take revenge on the in-laws, on her husband, and on Karin—the mistress—
and to reclaim the stolen time between mother and daughter,
their battle begins…
