시한부라서 흑막의 며느리가 되었는데

あらすじ

After losing her parents, Laria Losstree is saddled with a mountain of bills. Enter the archvillain, Duke Icardes, who agrees to pay off her debt, but only if she marries his son, Evan. Cool and distant, he’s not exactly ideal husband material, but that’s okay since Laria plans to secretly stash his money, then bounce! But when the duke starts acting suspiciously nice to her, Laria begins to wonder if he's on to her plan, and a battle of wits between archvillain and daughter-in-law begins!
