In a distant future. People all over the world became divided into two factions. The Opulents and The Necessitous. This people live very different lives, with Opulents on top of the food chain and Necessitous at the very bottom.

To differentiate the two, The Opulents developed a branding system called "N.C.S" a system in which Necessitous from their infantry be branded with a barcode on their skin. A proof of their status, A life of dread, poverty, starvation and slavery.

Chaeyeon came from the Necessitous faction. Living off of stealing from Opulents.

But during one heist an unfortunate event happened, and this will change hers, and probably all of the Necessitous faction's lives, forever.
