After being reborn as Croix Alloge, a villainess in a tragic R-19 novel, the heroine is ordered by her cruel father to seduce Duke Dielo Argenta and ruin his life. Disguised as his destined partner, she’s supposed to deceive him, but instead, she makes a bold choice: “Let’s get married. Just for one year.” What starts as a contract marriage for mutual benefit slowly turns into something deeper. But when the year ends and Croix tries to walk away, Dielo shows a possessive side she never expected. He’s not letting her go so easily.
