The Terminally Ill Miss Goes Undercover in the Villain’s Household

On the day her father died, leaving behind nothing but insurmountable debt, Livia discovered the truth, she had reincarnated as an extra in the very novel she once read before her death. That much was fine… but fate wasn’t kind. Once again, she was diagnosed with a terminal illness, the dreaded Black Blossom Disease, where dark flowers bloom across the skin until death. The only cure lay in the heirloom of the infamous villainous household, the Duke of Mercedes. There was no choice but to take the risk. “I’ll just help them a little, cure my disease with the heirloom, and then leave!” With that resolve, Livia slipped into the Duchy under the guise of a humble tutor. *** She found the heirloom. She cured her disease. Her purpose fulfilled. All that was left was to quietly disappear, like the side character she was destined to be. Or so she thought. “I'm sorry. Please, don’t leave me. I can’t live without you, teacher.” The Young Duke, once called a little devil, clung to her desperately. “I was meant to serve God and follow the Saintess… so why is it that I’ve come to you? Do you know the reason?” The holy knight, destined to protect the original female lead, swore his loyalty to her instead. “Miss Livia, my butterfly of destiny… is you.” The empire’s greatest information guild master began trying to seduce her. “Why not become my tutor instead? I’d be far more eager to have you than the Young Duke.” Even the Crown Prince, the novel's male lead, who was supposed to fall head over heels for the female lead, suddenly started trying to recruit her. And worst of all… “Try leaving, if you dare. But be ready to face the consequences.” The villain himself won’t let her go. 'Excuse me? wasn’t that a threat?!' “Just what on earth is happening here?!” All Livia wanted was to cure her illness. But somehow, everything has gone terribly, terribly wrong.
