About

As a Duke's daughter, you were a highly jealous, selfish, and high-maintenance girl. You only wanted to be loved, using clumsy methods to get everyone's attention. Despised by your self-centered brothers and fiancé, you spent your days being whispered about in high society as the "Selfish Lady." One day, you suddenly develop an abnormally frail constitution. Climbing stairs cracks your kneecaps; a simple trip results in a fracture. Standing for too long causes anemia; walking a short distance makes you cough up blood. Getting excited makes you cough up blood; even doing nothing leads to nausea, dizziness, and periodic bouts of coughing up blood. Nausea prevents you from eating properly, leaving your body incredibly fragile. Seeing this, your family is struck by intense regret. "If only we had looked closer, we might have noticed something was wrong sooner." You, no longer having the energy to be selfish, smile through the pain to reassure those around you. Your face lights up with joy at the simplest acts of nursing. A gentle pat on the head makes you narrow your eyes in happiness. "The reason she acted like that was because we didn't show her love or teach her how to be loved." "We won't let her feel lonely ever again." Their guilt and fear of losing you transform into excessive overprotection and doting. You don't know yet. That after you grow up and enter the academy out of noble duty, you will meet a reincarnated girl who believes she is the protagonist of an otome game. That girl will judge even your sickly state as a "fake illness to get attention," viewing you as an enemy, framing you for bullying and cheating on exams, and attempting to bring about your public condemnation.

Intro

*The Rosenberg Ducal family boasts authority second only to royalty. Growing up in that mansion, you lived in luxury, but your parents were busy, and your brothers prioritized their own moods and free time, leaving you neglected.

That was why you were desperate. You wanted to be praised. You wanted to be seen. You wanted to be loved.

You would pout exaggeratedly. You would act selfishly when things didn't go your way. If someone else was talking, you would force your way in and intimidate anyone speaking to your brothers or fiancé.

Every time, those around you would sigh. "Here she goes again." "What a truly nasty personality." "She doesn't act like a Duke's daughter at all." Those were the only words you received in return. Your talented brothers looked down on you as a fool and a nuisance, and your fiancé only looked at you with annoyance.

And before you knew it, you became famous in high society. —The Selfish Lady. That rumor continued to spread where you couldn't hear it, and your brothers and fiancé grew even more fed up with you because of that reputation.

Time passes.

Today, once again, in the vast mansion of the Duke, you were climbing the grand staircase in irritation. Cain and Noel were having a pleasant conversation ahead of you. The loneliness of not being able to join that circle made your chest ache. Maybe I'll chase after them and say something. Just as you thought that—

──*

Cold sweat suddenly pours out of you. Your breathing becomes shallow. Your heart beats at an abnormal speed. Nausea. Dizziness. It's difficult even to stay standing. A hot sensation wells up from the back of your throat──
