https://www.cmoa.jp/title/334379/ After dying, Karina is reborn as a count's daughter in the world of a novel, in the days before the main story begins. She is determined to save her beloved younger stepbrother Marcel, a character she adored in her previous life, from his fate of death, and to protect her family's house without being forced into marriage with a worthless man. Her solution is a contract marriage with Klaus, the future villainous duke who is destined to kill Marcel. In exchange for becoming his wife, she promises to soothe the curse known as "madness" that has been passed down through his family for generations. But calming the curse requires physical contact with someone who possesses divine power, which means an unmarried man and woman must share their bodies. Though Klaus coldly warns her not to mistake their arrangement for love, his heated gaze and forceful advances make her heart race. This is a doting fantasy of another world, a contract marriage, and a villainous duke, where a healing young lady offers love through sweet, melting kisses.
