Aisarenai Akuyaku Reijou ni Tensei shita no de Hirakinaotte Yaku ni Toushitara, Naze da ka Dekiai ga Hajimarimashita.

After saving a black cat, I found myself reincarnated as Alice—the villainess of a novel from my previous life. Destined to take my own life at the hands of a cold, distant husband, I refuse to accept that fate. My plan is simple: use him to survive. But just as I brace myself to play the role of the wicked wife, he catches me off guard with an unexpected proposal: “Will you enter a contract marriage with me and serve as my ornamental wife?” Wait, what? Now this icy duke is showering me with affection instead! And so begins our one-year contract marriage—a twisted arrangement that might just rewrite my tragic end.
