25 years ago, the Haesung Group lost their granddaughter Choi Eun Seok. The girl was found and raised by Seo Tae Su as one of his twin daughters, Seo Ji An and Seo Ji Su. They grew up rich, but their father was bankrupt, and they had to experience the hard life of a dirt spoon. Ji An is now a contract worker at Haesung Group who would do anything for a job, while Ji Su is an air-headed part-timer who has a one-sided crush on Seon U Hyeok. Unknown to her, U Hyeok was in love with Ji An in high school.
Choi Do Gyeong is Haesung Group's oldest grandson. He is gentle and kind, but being too good yet still single makes his employees spread weird rumors about him. He meets Ji An in a car accident and comes to know her sad situation, but his biggest shock is when his mother reveals that his lost sister is Ji An.
