How would you feel if you were born on the tracks; if your mother wore mink coats and your father barely made enough money to keep the lights on in his small apartment? How would you feel if your mother stepped out of your life when you were young, leaving you and your father in one of the poorest neighborhoods north of the Han? What if every day, after studying for hours and training with the school's dance troupe, you worked with your father to deliver dinners made by a cantankerous old man who couldn't give a about whether you were about to get evicted from your apartment or not? What if you met a group of five guys in your first year of high school that gave you a reason to wake up and work your fingers to the bone? What if you and those guys managed to find a...new way to make some quick, dirty cash? What if you got bad? What if, in your last year of high school, mama decides to show up again? What if she decides to enroll you in a college in one of the most affluent and ritzy neighborhoods in Gangnam, tearing you away from your father and your crew and placing you amongst a bunch of princesses that couldn't stand to even get dirt on their Armani slacks?

From delivering crappy kimchi boxed dinners and stripping junkyard cars of copper wire to smelling like Marc Jacobs and lapis lazulite cufflinks, Oh Se Hun has to jump the tracks every day. His heart belongs on the wrong side of the tracks while his body is riding in the first class cabin to a future of opulence and promise. That is, if he can manipulate everyone in his new posh world to boost him to the top.

You can take the boy out of the dirt, but you can't take the dirt out of the boy.
