Dara's delinquent days in high school is catching up on her as she got fired three times for each job in a matter of two days for smart mouthing her superiors. Now trying to hold a job, she had promised herself to live a normal, peaceful and an uncomplicated life so she could support her family. Mind the manners, be courteous. Be feminine. Having a lovelife is not one she had even gave a thought of. Never even thought to ask for one. Yet Donghae suddenly came in to her like a Dream Man and wrecked her peaceful life. And by wrecked, it means wrecked when she found out Donghae is just using her for a bet to win the affection of the girl of his dreams. Devastated, heartbroken, depressed, dejected. She cries herself off to sleep at night... ...NOT! Hell hath no fury like a woman scorned. He has no idea who he is dealing with. He's going to play his game but it will be by her rules. And he's not gonna like it.

Dara woke up in the hospital with 15 years of her life missing from her memory. From a simple and a bubbly girl trying to finish high school, she woke up as a CEO of one of the biggest music entertainment in the country. And no friends, no parents. Not even a boyfriend. But at least she got a husband. And he's the hottest guy she had ever laid eyes on who could probably melt her with just a glance. Problem is, he doesn't even talk to her. He doesn't even look at her without that cold stare. If she didn't know better, she thinks he hates her. What the hell happened???

After his brother abdicated the throne and the King denouncing him, Aiden was handed the responsibility of being the next heir to The Crown. It was too much big of a duty that was suddenly thrusted to him that Aiden was left feeling caged in. Being the King to rule a kingdom was never part of his dream. It was always his brother's but he was left with the duty of ensuring the threadbare peace between the South and the North advances by marrying the Northern Princess. After years of being drilled that Royalties was born without a choice as the future is already laid out at their feet, he swallowed the life that has been prepared for him. Sandy Park was a cheerful orphan whose idea of fun is shoplifting for the adrenaline it gives and watching the sun rise from the rooftop of her house. Or anyone else's. She loves the thrill of running away from the securities, taking a swim at a lake in a dark night, and exploring abandoned buildings in the wee hours. Their worlds meet at a by-chance encounter which left Aiden's well made-out rules and etiquette shattered. After taking a taste of a carefree life that Sandy had showed him in just a short time, Aiden was left wanting to make a choice. But will that choice uphold the peace in his country? Or will it cost him his Kingdom? Will it set him free? Or will he lose himself in the process?

Living her life as a girlfriend has been a shock for Dara. It is something which she had never even imagined to be. Something which she had never even thought of. Yet, here she was. Living it and enduring the difficulties of her new job. Sometimes, she doesn't know if she would want to kiss Donghae or kick him. Other times, all it takes is to get a smile from him and she would be submerged into a sensation of nothingness and engulfed by everything of him. Her life has become about him. Her existence has become his. So when fate decided to play her, that life she had with Donghae was put to the test as it threatens to pull them apart.. But no. She's not going to back down without a fight. Yes, this is one grueling job which will cost her countless overtime. And it was the only job she would do anything to keep.

Identical twins, Sandie and Darie, had been separated from the start of their parent's divorce and grew apart as different as any twins can be. Darie was the studious, sophisticated type who grew up with her mother, the heiress of the RanKim wealth and the owner of the Kim Industries. She has been brought up as the epitome of class and elegance and only had one goal in mind. To graduate high school with top honors and get into the best college. Sandie was the indomitable, imperious type who grew up with her father, one of the triad leaders of the Mark Of The Seven Sign Society, a highly infamous organization in the country. She has been brought up as spoiled and as pampered as much as her father can spoil and pamper her but she only had one goal in mind. To graduate high school and be a member of his father's circle. Their lives went into uproar as they were given the ultimate test of their patience when their dead grandfather played a joke on them on his will so they could receive the inheritance that each has been "dying for". Live as the other for a month. It was insane! They would have to be pretend to be each other for a month? In secret? It was ridiculous! Downright crazy!! But the lure of that inheritance made the twins agree. Darie would have to be Sandie, and Sandie would have to be Darie. Teemed with highschool rules that they had never encountered before, they tried to sail through the condition perfectly and flawlessly. But things may not be as easy as they thought it should be.
