Cha Eun Sang and her disabled mother both have to work hard, humiliating jobs, in order to support her older sister who's at university in America. Cha Eun Sang can't wait for her sister, who's her idol, to come back to Korea, and start earning money, so she can stop washing dishes and get a degree herself. However one day, Cha Eun Sang learns that her sister is about to get married, and realizes she'll never return to Korea, so she'll forever have to wash dishes. She resolves to go to America as well, and get better life. However, what she finds in America is far worse than she could ever imagine. Her sister is not only not getting married, but is also not at university, and is earning money working as a waitress, and maybe some shadier side jobs as well. After her sister notices her, they have a fight, she takes all of Cha Eun Sang's money and runs off, leaving her to cry and gather her broken dreams of the pavement. This entire exchange is observed by mysterious Kim Tan, who has completely different set of problems, but decides to take Cha Eun Sang's problems on, as well. At first reluctant to go with a guy who seems all to well acquainted with LAPD, she agrees to go with him simply so to not spend the night on the street. Kim Tan who is same age as her, leaves with no parents around, in a big, luxurious house, which makes her immediately assume he's a drug dealer. Instead of calming her down, he suggest he might also be dealing in human organs to support this life style. Meanwhile in Korea, we see group of privileged, spoiled high schoolers, the future 1% of Korean society, who all seem to be familiar with Kim Tan, and not many of them are fond of him. One of these is Choi Young Do, tall, handsome genius, with rancid personality, who learns that before getting his own stately resorts, he'll first be getting same aged, equally beautiful and "pleasant", step sister, Rachel Yoo, who's also engaged to be married to none other but his arch enemy, Kim Tan.
