>What Happened at St. John's College> I was possessed by a 19-year-old, devastated novel with only 1 percent of romance added. However, I didn't care that the novel I was possessed in was waste. 'Thank you for letting me possess a mob extra that doesn't even appear in the original work! Because there will be no contact with the characters at all! After that, I'm going to get my diploma, become the Marquis of Darling, and live happily ever after!' But, what a joke of fate this is... 'Here it is. The place where the tragedy takes place later...' Genevieve, who was supposed to enter <Four Gates Academy>, is admitted to <St. John's College> due to an incident. Are you lucky or unlucky? She realized it only after entering <St. John's College>. She knows that the point in time she was possessed was before the male lead and female lead appeared. However, when she entered her senior year with her relaxed mind. Fate brings another upheaval that will change her life. “Senior Genevieve Darling, that’s right.” Because the sub male lead in her novel, who is planning to commit genocide in the future, has come to visit her! However… "Sorry for bothering you. I will be quiet so as not to interfere with the assignment.” 'You were bullied, why are you apologizing?!' Even if the male lead in the black screen is docile, he is too mellow. No matter how dark his past is, this is too... From then on, Genevieve was determined. Even if I can't change all of the original works on my own, I'll make at least one good memory for Edward when he thinks of this time later ! “It’s okay, Edward. You can stay here.” Present good memories to the sub-male lead who will become the dark side in the future! Can Genevieve's goal be achieved?
