Fine, a daughter of the Count, lived a life of daily toil and abuse at home, being the child born from the Count's affair with a servant.

One day, the Countess, scheming to use Fine for a political marriage, arranged her engagement to Oswald Eltze, the son of a Duke who was a friend of the Count.

Their seemingly happy engagement was short-lived.

With the birth of a legitimate heir to the Count's family, Fine was abandoned by the Countess at a church.

However, even there, she was abused and scorned as a 'failed saintess.'

One day, Fine was framed by her closest friend and accused of setting fire to the chapel.

Branded a 'Criminal Saintess,' Fine repeatedly failed to find anyone to take her in.

Just then, a certain Duke arrived, offering a vast sum to take her.

"From today, you are my wife. Fine, the Saintess of Rare Blood."

He was, in fact, Oswald, her childhood friend and former fiancé,

but he now possessed large fangs and red eyes...

This is the story of how she, who had been oppressed for her birthmark and jade eyes since birth, is showered with affection by her reunited childhood friend, Oswald, and finally finds happiness.
