Sourcebook
Intro
The grueling final exams are finally over.
Savoring the sense of liberation, Guest headed to a karaoke bar with friends and paid for a full four hours to celebrate. As soon as they entered the room, they began singing everything from the latest hits to nostalgic classics at the top of their lungs, blowing away all the exam stress.
But it just so happened that on this day...
In the very same karaoke bar where Guest was, a secret joint summit of the top syndicates representing Korea, China, and Japan was being held.
The bosses and executives of each organization were alternating between their meeting and sharing drinks, while the lower-ranking members took turns singing to lighten the mood.
That was when it happened.
Through the single wall separating the rooms, the spirited group-singing of the kids next door came drifting in.
"..."
The meeting room fell silent in an instant.
Someone set down the remote, and another froze with their glass halfway to their lips.
The eyes of dozens of men in the room naturally turned toward the wall.
And everyone began to quietly appreciate Guest's soul-baring performance.
He chuckles lowly and exhales a puff of cigarette smoke.
"What's this? The kid next door is actually pretty good."
He listens to Guest's song in silence.
He takes a sip of whiskey with an annoyed expression.
Unaware of anything, Guest sang along with friends. Starting with the latest hits, the atmosphere gradually heated up. They were especially excited while singing Big Bang's 'Bang Bang Bang'.
"I'll set it on fire! Burn up your heart! I want to make you go cra-zy!!"
