Hye-na was born into a wealthy family, and the family's riches gave her a princess-like life from the moment she was born. But can money buy happiness? Can it really purchase the lifelong happiness Hye-na desires?
Her affections are caught between two people - one is a penniless butler, the other is the second son of a wealthy conglomerate. Whose way will Hye-na's heart lean towards?
In theory, a princess and the second son of a wealthy conglomerate are the perfect match, but there exists a master-servant relationship between the princess and the butler. The daily ups and downs have turned this pair of master and servant into a pair of loving enemies. Between love, pride, and status, what choices will these men and women of different identities make?
In the upper echelons of Korean society, where celebrities gather and the rich flow, Kang Hye-na is someone that men yearn for, and women fear and despise. As the sole heir of the largest conglomerate company, Kangsan Group, Hye-na possesses both wealth and beauty. She is the owner of "Lady Castal," living a princess-like life with her servants. Her parents passed away in a plane crash when they were young, and Hye-na was raised by her strict grandfather. Despite her grandfather treating her like a princess and giving her everything she wanted, Hye-na did not feel any warmth from family or friends during her growth. Because of this, Hye-na openly disregards others' feelings, believing that the whole world revolves around her alone. Whenever she opens her mouth, regardless of who the person is, she only says, "Shut up," "Get lost," "It's over."
When it comes to horseback riding, fencing, and clay shooting, Hye-na has skills at a national representative level. However, the only reason she thinks these skills can humiliate her men or put them in an awkward situation.
[Hye-na's personal note] Until one day, by chance, I met Seo Dong-chan, the man who turned my life upside down. He not only made me do community service, but he even kidnapped me... Now he's become the new butler! This guy is definitely trouble. He's a weed with so much perseverance that even herbicides can't make this weed give in. Even if you step on him, crush him, bite him, he still doesn't run away. Seo Dong-chan, I know I don't have a good impression of this man. What makes me uneasy is that I've finally realized this will be my game... I have no other choice now. If you can't leave, then I'll make you leave my way.
