The main story begins in the final year of high school for two of the primary character: Lee Ja-young (Choi Ji-Woo, Stairway to Heaven, Winter Sonata) and Lee Shin-hee (Park Sun-Young). Ja-young is a smart and talented girl with a bright future ahead of her. She has consistently ranked as the number one student and hopes to go to a good college. The catch is that she comes from a poor family and lives in the basement of Shin-hee’s family. Ja-young's father works for Shin-hee's father, who is a powerful senator. Shin-hee is opposite of Ja-young. She lacks book smarts and makes up for it by being a rich spoiled brat.
