Eric Mun: Kang Tae Joo is selfish, proud and vain. Hates anything that’s complicated and despises to think but he has a warm heart. Has been working for an event company for three years (Palace Department Store Planning Team). He’s popular with women, handsome and well-mannered to boot. Good at card games, billiards and poker and he hardly ever loses. Perfect except for the fact that he has nothing.

Jung Yoo Mi: Han Eun Soo is Simple, bold, and optimistic. Too honest to the extent that she may be described as blunt and absurd. She dearly loves her half-sister, Ji-soo.

Yoon Ji Hye: Cha Hye Lin is free, liberal, and genuine. She has been very successful with her own designer brand. Put under the spotlight for establishing her own business, unlike other kids of the rich and the famous. But she’s well aware of the fact that her family background worked to her advantage for her success. She seems cold and arrogant but deep down, she has a strong desire for true love.

Lee Kyu Han: Shin Joon Hyuk is rational, perfectionist, and introvert. The power figure of the Palace Department Store who has taken the elite course. He seems like the perfect guy with everything going for him, but deep inside, he has a sense of inferiority about his roots and feels isolated.
