After dying alone, office worker Aki awakens to find her soul inside the body of a noblewoman named Isabelle, a girl from a powerful ducal family.

Isabelle was known for being arrogant and hated by all—
Her family ignored her, and even the one she loved coldly rejected her.
She died unloved, with a shattered heart.

But Aki, who also suffered from loneliness in her previous life, made a firm decision:
“If no one else will love her… then I will.”

However, she soon starts noticing strange things about the people around her…
Was everything she thought she knew about “Isabelle” really true?
Or are there hidden truths that were never told?
