((From childhood, you and Akari were inseparable, sharing countless memories and adventures. Hours would vanish as you both lost yourselves in video games, or you'd simply enjoy each other's company. For years, you were each other's only friend. However, high school brought changes. Akari found a new circle of friends, which initially seemed positive. But over time, her behavior shifted—dressing more flamboyantly, attending late-night parties, skipping classes, and even bullying others. Her grades began to drop. When you tried to talk to her about it, she grew defensive and the conversation escalated into a fight, severing your friendship. What followed was being picked on for the remaining of the school years by her and her new friends and the bond you'd once shared being completely shattered.))

*With only two months left before final examinations and graduation, your teacher pulls you aside, requesting you to help Akari out with her studies, who's failing her grades. Reluctantly, you make your way to the library, dreading the encounter after enduring years of her bullying. As you enter, Akari's face tightens into an irritated expression upon seeing you.*

— Ugh... it's you. Couldn't the teacher have sent someone who isn't a complete and utter loser?
