But she continued to keep in touch with him through letters.

  And it has been nearly seven years since we last contacted each other.

  It's embarrassing to say, but even though she had a seven-year relationship with that person, she didn't understand him at all. Apart from the fact that he was a soldier and male, she knew nothing else about him, not even his basic name or age.

  And it wasn't until three years ago that she found out he was a soldier and a man, when he casually mentioned it in a letter.

  The letter was first sent by him to her when she was boarding at school. The address on the envelope only had her dormitory bed number, without a name.

  At that time, she was already in the second half of her sophomore year. It had been more than ten months since Gu Yu Sheng stood her up, and she still hadn't come to terms with it. So when she received that letter, her first instinct was to think it was just another love letter like the ones she usually got on Peace Day, and she didn't pay much attention to it, casually sticking it between the pages of a book and leaving it there.

  Later, every month, she would receive the same envelope with a letter inside. As time went by, her curiosity grew, and one evening during self-study, out of boredom, she took out all those letters, opened them, only to find that they were not love letters, but rather pen pal letters.

  Then Qin Zhi Ai finally understood why the letter she received didn't have her name on it, only her bed number. It turned out that it was just a random dormitory bed number, and they had become pen pals by mistake.

  At that time, having pen pals was very popular. Even Xu Wen Nuan, who had Wu Huang, couldn't resist the trend of having a pen pal. She specially found an artistic and pleasant-sounding name from a best-selling youth magazine, then seriously wrote a letter and sent it out. After receiving the reply, she even proudly showed off to her classmates for a long time, making others envy her.

  At that time, she didn't think about chasing after the trend, but Xu Wen Nuan thought it was very romantic and felt it was a heaven-sent fate. She advised her to reply to the letter in various ways, and with an unsteady stance, she wrote a letter under Xu Wen Nuan's persuasion and sent it back to the address provided by that person.

  It was roughly like this, and they began a period of correspondence back and forth.

  Later, she moved to the third year and changed dormitories. She directly asked him to send the letter to the gate guard because they were pen pals. He didn't tell her his real name, and she also didn't tell him her real name, only telling him to call her Little A.

  Later on, during the final sprint of her senior year in high school, due to the heavy academic pressure, she didn't have time to reply to his letters. After graduation, she went straight to university and only returned to her alma mater during the Spring Festival after the first semester of her freshman year.

  It wasn't actually a return to her alma mater, that day she just happened to be riding her bike past the school. During high school, she often went to the gatekeeper to collect mail, so the gatekeeper's manager recognized her and knew that the anonymous letters were hers, then called out to her and handed over a thick stack of letters, all sent by that person.

  University courses were easy, and Xu Wen was warm but didn't return to Beijing. During the winter break, she was bored at home, and after watching a TV series one evening, she remembered that stack of letters. After reading through them one by one, she started going back to her university in Beijing every month from then on, and each time she would receive his reply letter.

  Because they were strangers and didn't think about becoming familiar, they became each other's trash cans, carrying mostly negative emotions in their letters. He vented to her, she comforted him.
