While guiding the second manifestation of her classmate, Liliope suddenly realizes she's possessed by a book. And to make matters worse, she's possessing an extra who can't withstand the power of the male lead, an S-class Transcendent, and ends up dying. It's not even the mastermind's younger brother, Hiaquin, who was added in just to spice things up. "The original? Who cares? I'm going to die!" I thought it would be over if I found and saved the female lead, Milia, before Acteon's second manifestation, and quietly ran away with my younger brother to find a way to live— "It's all thanks to you, senior. I'm alive and well." Not only did I accidentally heal the male lead's trauma instead of the female lead, but I was also called in by the professors and had my rank checked again. "Cadet Liliope Oritis's guide rank is... S-class." Damn it. Why the heck is my rank like this?(Source: Kakaopage, translated)
