Hahm Eun-jung, former member of the T-ARA group, will play a dual role: that of Oh Jang-mi, a woman of integrity dreaming of opening her own restaurant, and that of Ma Se-rin, a capricious heiress and only granddaughter of the president of the Dream group. These twin sisters, separated by a cruel twist of fate, will see their paths cross again through 2 brothers: Kang Baek-ho (Yoon Sun-woo)a benevolent lawyer, and Kang Jun-ho (Park Gun-il)a chef as cool as he is passionate about his craft.

Oh Jang-mithe eldest, is a warm-hearted, courageous woman with a strong sense of justice. Gifted in the kitchen, she works tirelessly to realize her dream of opening her own restaurant. Smiling and persevering, she takes on a series of odd jobs, but refuses to let difficulties get her down.

Ma Seo-rinthe youngest, is the sole heiress of the conglomerate Dream Group. Spoiled, daring and carefree, she lives in excess, knowing neither fear nor limits. Ready to do anything to get what she wants, she crushes anyone who gets in her way, until fate catches up with her.

Oh Hyun-kyung will play the role of Chae Hwa-young, a graceful former star who'll do anything to take control of the Dream Group. Behind her elegance lies a determined woman, ready to sacrifice everything to achieve her goals.

Yoon Sun-woo lends his features to a fair and caring lawyer, while Park Gun-il plays his brother, an aloof man whose shell begins to crack when he comes into contact with Oh Jang-mi. Last but not least, Kim Min-seol will play Jin Hong-joo, an ambitious Dream Hotel employee who is jealous of Jang-mi and will do anything to get what she wants.
