Characters: 

Hwang Tiffany: 

A 22-year-old girl that has been working all her life in order to beat her older brother, Siwon.  She even went as far as to change her last name in order to prove that she can do everything herself. She's determined, independent, and can seem a little cold-hearted at first.  In reality, however, she's just a girl that tries to keep everything to herself because she's too scared to let anyone else in.

Eunhyuk (Lee Hyuk Jae): 

A 25-year-old boy that has grown up with expectations for all his life.  He breaks all the rules, is irresponsible, and has no goal in life.  He's a player and not afraid to admit it.  His parents have almost given up on him.  The truth is, he could do everything if he just tried, but he doesn't want to.  He has no ambition and just goes with the flow.  

Choi Siwon: 

A 24-year-old boy who is the crowning jewel of his family.  He does everything effortlessly.  He loves his sister and has always been supportive of her.  He has a warm heart, but can be a little clueless sometimes.  
 

Description: 

Tiffany finds out that her father's company has already decided that her brother Siwon will be the heir of the company.  She feels crushed because that's what she had been working towards for her entire life.  She feels hopeless until her father gives her another choice.  Her father tells her that she should get married into this other company's household, whose only son is lazy and refuses to work.  Then, they could have a partnership with this equally powerful company, and she can end up being in charge of this other company, since the son is useless.  She agrees, feeling that this is the perfect plan.  

What if this arranged marriage isn't all that it cuts out to be, though?  She now has a husband that is not only annoying, but totally different from her in every single way.  He's immature, lazy, irresponsible, and just completely intolerable.  And to him, she's just uptight, stubborn, too proper, and cold.  This marriage seems like a disaster until they realize they're slowly changing for each other.... Will Tiffany be able to survive through the marriage for her dream, or will it end up back into a disaster?
