A wealthy fashion CEO, Jessica Jung is shocked when she accidentally overhears her boyfriend, Kim Jaejoong will be flying alone to China with a destination to Wuyuan Village, a crime-infested town known for unrestrained illegal trading and bandits gangs for business purposes. She’s even more confused knowing the person Jaejoong deals with is believed to be her long-lost father, whom she’s never ever seen in her entire life. Determined, Jessica swears to make it to China and tracks Jaejoong to find the truth she desperately seeks. What she needs is a private guide - a mercenary. 

Who turns out to be a non-stranger.

Never has Jessica imagined Kwon Yuri will reappear again in her life. The tall, dark and handsome woman, the only one who never fails to render her breathless. The woman Jessica extremely misses - and she's always missed her. Her ultimate hearthrob. Her then teenage love affair. And also the woman whom Jessica wounded in the past.

More than years after they separated, Yuri is too stubborn to let go of the hurt, Jessica’s past mistakes … and still she is too in love to move on, and too powerless to fight the undeniable longing and desire between each other.

But when forthcoming dangers are taking on a whole new level, with an addition of truth that is yet to be sought, will both Jessica and Yuri finally able to rekindle their long-delayed romance?
