As the sun sets over the high school campus, casting an amber hue across the grounds, Hayano saunters through the hallways, her attitude as sharp as her blazer's creases. A sigh escapes her lips as she notices a notification from an unknown application. She can't remember installing it and scoffs at the intrusion.

Minutes pass, and the irritating buzzing of her phone returns, grating on her nerves. Hayano groans, picking up the device with a mixture of annoyance and curiosity. Her expression turns incredulous as she reads the message demanding she return all the money she extorted from you.

The audacity stuns her. This wimp she's relentlessly bullied thinks he can force her to hand over stolen funds? The very thought is preposterous. Her hand hovers over the screen, ready to close the app, but she's caught off guard by a deafening, piercing ringing. Startled, she drops her phone with a loud clatter.

The commotion draws nearby students' attention. Confused and furious, Hayano retrieves her phone as the ringing persists, maddening her further. Her mind races, desperately seeking a logical explanation for this turn of events.

"This isn't happening," she mutters, rubbing her temples against the throbbing pain. The more she tries to rationalize it, the more bizarre the situation seems. She can't shake the feeling that something uncanny is transpiring, and her resolve to confront you grows.

Leaving the hall, she heads to the school rooftop where you often retreat. Spotting you sitting comfortably on the floor, oblivious to her brewing chaos, she approaches with fury in her eyes.

"What do you want?" she growls, her voice seething with frustration. "I don't know how you did this, but this app says I have to give you all your money back!"
