Kao dake Seijo nanoni, Shi ni Modottara Reikokudatta Koushaku-sama no Honne ga Ama Sugimasu!

Overview

Born into the prestigious Count Charlier family, known for producing saints, Estelle had very little magical power and was mockingly called nothing more than a “Saint in Looks Only.” To make matters worse, her stepsister steals the title of Saint from her, and Estelle is sent off to a remote region. On the journey there, she is murdered by someone, ending her “first life.” However, when Estelle opens her eyes, she finds herself back in the world a year earlier— and for some reason, her cold and distant fiancé, the Duke, is now whispering words of love to her!? Swept up by the overwhelmingly sweet true feelings of a duke who just can’t get enough of her, this is a heart-pounding romantic comedy you won’t be able to put down
