Nian Jianyue's father was an ordinary letter sorter at the post office and had never done anything important in his life. After his death, Nian Jianyue packed up his belongings and found a whole cabinet of unsent letters. The recipients all wrote about her, from when she was seven to twenty-seven. She opened each envelope and read the words that her father had never said in his life. And in the last letter, there was a remittance slip and a photo of a stranger. There was only one line in the letter: "Yue'er, this family harmed your mother back then. Dad spent twenty years waiting for an apology. Keep the money, don't hate it."
