All Alone

At age eighteen, all citizens are given a concentration that will determine their fields of study. A small empty square on their wrist will gain a color corresponding to their skill set. Everyone's fear is that their square color is black, meaning they are destined for a life of crime.

When Jungkook turns eighteen, he waits anxiously for his square to gain color, only to be presented with a blank square. He is shunned by his family, having to struggle through high school while trying to figure out what to do for the rest of his life.

Jungkook's life gets flipped upside down on the day of his twenty-first birthday when the store he works at is robbed with Jungkook at the cash register. Fearing for his life he believes he is going to die, only to be saved by a figure in black with a mask covering his face.

To make things even worse, Jungkook suddenly becomes the target of one of the largest drug syndicates, solely because of his new connection to his savior and five other men who turn out to be the biggest crime lords in Seoul.
What happens then, you ask?

Well, then the blank world Jungkook always saw starts to drip with black, just a little bit.
