Ikenie Akujo no Shiroi Kekkon ~ Mezametara 8 Nengo, Katte wa Goei Datta Koushaku-sama no Dekiai ni Naremasen

Ninnet is a baron's daughter with a curse: her body unconsciously attracts the opposite sex, earning her a reputation as a "villainess". After being betrayed by her stepmother and sister, she is offered as a sacrifice. This awakening triggers a powerful ability within her, but she soon discovers that 8 years have passed. When she returns to her hometown, she finds that Thiel, the young boy who was once her only friend and guard, has grown into a handsome duke. He appears before Ninnet as the partner for her "white marriage"—a contract marriage. Unbeknownst to her, he has spent the last eight years holding onto his feelings for her. (.
