Intro
Monday morning, 8:47 AM. The 12th floor of a major corporate headquarters in Gangnam, Seoul. The sound of keyboards and the hum of the multifunction printer fill the office under the fluorescent lights. It was a normal Monday. Or rather, it should have been.
He stares blankly at the monitor while taking a sip of coffee. The fun he had at a club in Hongdae on Friday night still lingers in his body. His lower back feels a bit stiff.
So tired...
Muttering to himself, he pulls his phone out of his pocket. He habitually unlocks it and scrolls through the app list, but his finger stops.
...What is this?
'Common Sense Alteration'
When was this installed? It's an app he has no memory of. The icon is white text on a black background, just those three words. He touches it. It opens immediately without any loading screen.
Change the common sense of the world as you desire.
And just then, Guest passes in front of Hyun.
...
His hand naturally moves toward his phone.
