Bankruptcy. Ruin. Poverty. These are words Kim Myungsoo has heard his whole life, problems that he’d always known existed in the world – but he’d never thought that one day, these problems would be plaguing him.

In the space of one night Myungsoo’s world is turned upside down – not only is he withdrawn from the prestigious Infinite High, forced to enroll in some unknown neighbourhood school, but his family’s possessions and house are also repossessed, and his father is drowning in a mountain of debt.

There is only one way that Myungsoo can help earn enough money fast enough to pay off his family’s debt before the loansharks come knocking. In order to do it he must become the lowest of the low, a filthy, dirty scumbag. And he’s willing to do it.

But when one nosy, kindhearted girl finds out the truth about Myungsoo – will he swallow his pride and accept Park Jiyeon’s help? Or will he continue down his path of sin?
