A love story between the Crown Prince of Korea, a typical girl and a playboy, who knew something so small, would change everything?

Choi Eunsoo had it all, the looks, brains and beauty. She was one of the rare girls at Seoul University, she was kind and courteous to people. She had breeding and elegance. Being the only child and only girl in her family, she grew up without a female companion, but good for her she has one older cousin, Zhang Yixing, or Lay as others call him.

Eunsoo was raised well, she wasn’t spoiled but her parents made sure that she was provided for.

For about two years she was steadily dating someone. Until something happened.

Not everyone knew about them, except for a few close friends.

He was Lee Howon, or Hoya.

South Korea’s Crown Prince, he was next in line for the throne.

Lee Howon was born in the royal family, he grew up trained to be the future ruler of the country. He is a quiet person, but he is comfortable with the people he knows and trusts. Hoya isn’t one of those rebellious types, rather he was obedient to his elders and he followed their demands.

He didn’t know when he started to fall for the clumsy girl from his class, but it just came naturally.

Hoya loved her dearly, in his own quiet way he protected her. But what if his parents, the king and the queen arranged him to marry someone. They claimed that they were arranged ever since birth.
