The day my father died, leaving behind nothing but crushing debt, Livia realized she’d been reincarnated as an extra in the very novel she’d been reading before she died in her past life. That much was fine, but… She’s terminal again—this time with the “Black-Blossom” disease, where black flowers bloom on the skin and you die. The only way to cure it is with the heirloom of this world’s power behind the scenes: the Ducal House of Mercedes. Well, it can’t be helped. “I’ll lend a hand just enough to get the heirloom, cure myself, and then I’m out!” And so Livia slipped into the Mercedes household under a false identity as a live-in tutor. She found the heirloom and cured her illness. With her goal achieved, she planned to fade away quietly like a proper side character, but… “I was wrong. Please don’t go. I can’t live without you, Teacher.” The young lord known as a little devil clung to her, begging her not to leave. “I, who ought to serve God and attend the saintess—do you know why I have come to you?” The holy knight who should have followed the original heroine swore a knight’s vow to me. “Ms. Livia, you are the butterfly of my destiny.” The master of the empire’s greatest information guild even tried to seduce me, “Instead of the young lord, would you become the prince’s tutor? I find you very desirable.” And the male lead, who was supposed to give his heart and soul to the original heroine, for some reason started trying to recruit me. Most of all… “If you’re going to leave, then try it—if you’re ready to deal with the consequences.” Excuse me, isn’t that a threat…? “What on earth is going on here?!” I only wanted to cure my disease, but something has gone very, very wrong.
