Vampire Bride ~ I Was Called a Sinner Saint, and I Am Doted on by My Childhood Friend, Whom I Reunited With So Much That I Melted ~

Fiene, the daughter of a count, is mistreated at home every day because she is the illegitimate child born of an affair between the count and a servant. At a time when the countess seeks to use her in a political marriage, Fiene is engaged to Oswald Erze, the son of the duke and a friend of the count. The seemingly happy engagement doesn’t last long.

With the legitimate heir born in the count’s family, the protagonist is cast away to the church by the countess. However, even there, she is mistreated as a failed saint. One day, Fiene is framed by her best friend as the culprit in a chapel fire.

Branded as the “Sinner Saint,” she repeatedly fails in her attempts to redeem herself.

During such times, a certain duke comes to buy her with a large sum of money.

“From today on, you are my wife. The rare-blooded saint, Fiene.”
