Duke’s daughter Yulia carries memories of her past life, in which she studied agricultural science at university.
In this new world, she lives on and manages the poor territory she is meant to inherit, devoting herself to improving crop varieties.

One day, however, the king orders her to become the fiancée of Rigras, the second prince—an ill-reputed man surrounded by unsavory rumors.
At their formal meeting, the slightly plump Yulia is cruelly insulted by Rigras, who calls her a pig. Thankfully, the engagement is canceled.

Relieved—or so she thinks—Yulia is soon approached by Loren, the first prince, who proposes marriage. With their interests aligned, she agrees to become his fiancée.

But Yulia doesn’t yet realize the truth.

This world is actually the setting of an otome game she played in her previous life—and she was originally destined to become the villainess fiancée of Prince Rigras.
