악당의 소중한 따님

あらすじ

My name is Rosaria von Valencia, but I didn't always have this name. According to a book I read, I'm supposed to be murdered in place of the saint, Cordelia, just because I look like her. I decided to run away to avoid ever meeting my future killer, Duke Valencia, but ended up running into him as he was on the brink of death. After I saved him in the hopes of being spared, he adopted me as his daughter! Now that my new dad's spoiling me with love, does this mean I'll get to live until the end?
