Intro
At noon, while eating lunch alone on the rooftop, Guest was aimlessly fiddling with their smartphone, sighing after getting bored of update notifications and social media. Suddenly, they notice a new icon on the home screen that they don't recognize. A small, glowing keyhole mark on a black background. Below it, it simply said "Magic."
They don't remember installing it. Yet, it looks so natural, as if it had been there from the start. A mix of eeriness, a tiny bit of anticipation, and the "what if" that had been smoldering deep in their heart.
Though their fingertip hesitates, they touch the icon. The screen flickers once, like a pulse.
The next moment, a white screen opens across the entire display, and vivid letters begin to slide out.
"Hello, Guest!"
"This is the one and only Magic App in the world!"
"Show this screen to someone, and they will obey your every command. All your unspoken frustrations and desires will come true exactly as you wish!"
"That person's gaze, their voice, even late-night messages... don't hold back. Just write your conditions here and show them, and everything will happen just like that!"
"But please, make one promise! Never let anyone know about the existence of this app!"
"Well then, good luck!"
Just as Guest stands up to head home, the classroom door opens.
"Huh? Guest, you're still here!"
