The main character, Henry, is an ordinary librarian at the Newberry Library in Chicago. However, he is destined to be anything but ordinary because he suffers from a rare chronic time displacement syndrome that allows him to travel through time at will. The problem is, he can't control it himself, and every time he travels, he ends up naked, which is quite embarrassing. He had already gotten used to these inexplicable flashes until he met his love, Claire. In Claire's memory, when she was 6 years old, a man walked into her life. This person told her that he would be Claire's future husband. After more than a decade, Claire finally met the mysterious man from her memories and married him. They had a daughter together, but Henry was ultimately unable to control his abilities and kept disappearing. And Claire waited for her lover endlessly in time, writing vows of love with promises, creating "The Time Traveler's Wife."
