Jang Yoon-Ha is the youngest daughter of a chaebol (family owned conglomeration). Even though her family is extremely wealthy, she holds a part-time job at a food market. She hides her background as an heiress and attempts to find a man that loves her for herself.
Side note: You would mostly be watching this show for this couple (Chang soo and Ji Yi). Definitely not your traditional KDrama relationship. Thank goodness for that. ^_^
