Kwon, a language school instructor, stops by her old workplace and receives a thick envelope addressed to her. A Japanese instructor named Mori had proposed to her two years ago. She turned him down. Mori had immediately gone back to Japan, but now was back in Korea looking for her. The envelope enclosed letters he had written to her during his search through Seoul. After Kwon finishes the first letter in the lobby, she grows faint coming down the staircase and drops the letters. She gathers them off the floor and sees there are no dates on the letters. She now has no way of knowing the order in which they were written.
