Choi Yena, an overworked office worker, didn't think she'd have much to look forward to in her life. Apart from the few parties thrown by her coworkers and friends, she never went out much. She wasn't introverted, far from it, but she didn't know anything besides work. She relied on it as much as the papers filled with reports and statistics relied on her.

Jo Yuri, a young woman tied to the waters unable to leave, would love nothing more than to run away from her problems in Sokcho. Everything about her life was static despite living in a city with known tourists spots. She watched people come and go while she alone stayed.

These two women who had everything and nothing in common met one day; and perhaps, through the ebb and flow of the waves, they might find a piece of themselves lost in each other.

And Hyewon? She's just there for the ride :)
