Lee Yeo Reum (Seolhyun) is a young woman whose career and life are going very well: She has just been awarded permanent contract status at work, and she has a boyfriend she likes very much. But work is starting to get stressful, and then she is hit with a double whammy of misfortune. Her mother dies in a tragic accident just moments after she is dumped by her boyfriend. Feeling utterly dejected and burned out, she decides to quit her job, head to the seaside, and do absolutely nothing for a while – at least until she can recharge her batteries and recover mentally.
She moves to a small seaside village named Angok. And it is here that she meets An Dae Beom (Im Siwan), a stuttering librarian who also has his share of skeletons in the closet. Many years ago, he was a math prodigy with a bright academic future ahead of him. But circumstances have forced him away from the big city and the scholastic life. What will happen when these two lost souls meet – and will a spell of “doing nothing” in this small town really cure their ills?
