But after the deaths of their parents, the siblings are sent to an orphanage where they tearfully part once they get adopted into different families.
In Korea, Ha-neul is a given a new name, Park Hae-won, and grows up in a wealthy, loving family, so much so that she finds it suffocating. Her adoptive mother (Sunwoo Eun-sook) treats Ha-neul like her dead biological daughter, while her adoptive brother Park Tae-won (Yoo Ha-joon) is obsessed with her.
In Australia, Gun lives a life of destitution with his adoptive father Goo Kyung-taek (Lee Ki-yeol) and adoptive sister Goo Hyo-joo (Lee Yeon-hee). He becomes a small-time gangster whose main talents are swindling and fighting. When he hears from his best friend Goo Sung-chan (Kang Sung-jin) that his sister Ha-neul was adopted by a rich family and is now living like a princess, he decides to return to his native country in order to con Ha-neul into giving him money. Hyo-joo, who's nursed a crush on him for a long time, follows Gun to Korea.
