Anna, a noblewoman, has memories of living as a Japanese person in a past life. In that life, she had a terrible existence, unable to get along with her husband or children.

Even in this new world where she was reborn, her birth mother passed away, and she endured daily abuse from her birth father, stepmother, and half-sister. Her half-sister used Anna's name to chase after men, dragging Anna's reputation through the mud. Upon reaching adulthood, Anna is married off as a wife purely for show to a Marquis who lost his beloved wife.

She thought it best not to expect anything from the start, believing she would be content just living quietly alone in the annex. However, as she spends time with Edward, the Marquis's son who is rumored to be a problem child, she finds herself not just accepted as family, but utterly doted upon...

This is the story of Anna, who had given up on happiness, as she finds it with the Marquis and Edward. It's a happy ending.
