Woojin and Jiwoo were both orphaned as a child. They wandered aimlessly asking for scraps of food to random passerbys and took shelter in run down factories or under tunnels. Their bond was similar to that of siblings, there wasn't anyone else they can trust but each other. At a later date they were taken in by a korean gang indebted to them for saving the life of their boss.

Somin grew up in a sleazy wh0rehouse and at the age of 15 was forced by her own mother to sell her body to the malicious gazes of  men that wandered about the loud ,dangerous ,nightclub-filled streets of the slums of western Seoul. She was sick of it, she wanted to run away, to be free. And a fateful night came turning her life upside down as she locked eyes with a tall,lean, handsome man.

Taehyung never revealed his name to anyone, and was only known with the alias J.Seph. He was a gambit through and through and if challenged with a card game, you'll see to it by the end of the night you'll be bankrupt. But when taunted by a gorgeous blonde minx to a game of hearts, he was drained of alll emotion but shock when he lost to her so easily.

All 4 of them viewed themselves as petty, miserable lowlifes, who never knew that they would find peace at the most random of people that you would encounter.
