Meet Kim Hayoon, the only daughter of a Sergeant in the US Army who struggles getting through the day with the constant worry that follows along the inevitable deployment. But that's not all. Her brother is a soldier as well who loves the military life to the point of no return. As much as she loves and adores the only two male figures in her life just as much does she hate the included military regulations keeping her enclosed. That's until a certain soldier comes along and sweeps her off her feet with his rough features and crooked smile. Perhaps, Hayoon will be able to find happiness despite her fear of losing the ones she loves the most?
