I Became the Daughter-in-Law of the Villain Because I'm Terminally Ill!

I've reincarnated as the young daughter-in-law of a villain who was taken in for his deceptive plans. The problem is that I'm terminally ill, so I'm going to die when I become an adult. "Luckily, I know how to cure it, but..." If I don't die at the right time, my father-in-law—no, the villain, Duke Ecarde—might kill me just to achieve his goals! But what kind of kid could actually adjust to this kind of household? "I want to live happily with Father and Evan for a long time... cough! Cough!" Me. I'm "that kid." --- The final villain is being deceived by his young time-limited daughter in law who was possessed. If I die at the right time, I will marry his son. The problem is, I already know the cure! And I don't want to die, but if I don't get killed now, then I won't die quietly. "Daddy, I love you so much. You are the most handsome man in the world. Cough, cough!" "Evan, shall we read a fairy tale book together until we fall asleep?" She will have to act a little better to let his guard down. Then, she would be able to do a great job. I think I'll have to leave secretly after I get better. I have to make a lot of money and buy land under pseudonyms. "Call all the council members on the continent. My daughter-in-law has to live." Father? Shouldn't I be thrown away…? "If you die, I'll follow you unconditionally. I can't live in a world without you." Husband? You’re acting strange, too… You don’t love anyone, do you? Even- "Who is this, Kyle Ravonis? The man who seduced my daughter-in-law deserves to die." "Even if you cheated on me with another man, I will never break up with you." You must have misunderstood my other name! "When did this start, huh? You said you wanted to live as a sweet couple, but you tried to run away by creating a new identity behind our back?" I want to quietly disappear, not die! I didn't know my husband, who has been like a friend to me ever since we were young, would come to me with such sore eyes. "You're still my wife on paper. Live as my wife, and die as my wife." "Evan?" "You've shown me both heaven and hell…" his reddened eyes locked me up, "You'll never get away from me no matter where you go." --- **Original Webtoon:** Daum, KakaoPage **Official Translations:** * Indonesian / Bahasa Indonesia * Japanese / 日本語
