On the first day Xu Mian became a postman, she received a love letter she had written seven years ago - the recipient was Jiang An, the boy who died in the summer when he was eighteen. But when she followed the address and pushed open the door of the old post office, she saw the person who was supposed to disappear tapping the postmark with his head down, and behind him were piles of letters from different time and space.
