It was about four years ago when she sent him a letter but didn't receive a reply for a long time.

  At that time, she thought that the correspondence with that person would finally come to an end.

  After all, having pen pals is just a fleeting infatuation and impulse of youth, who would really cherish it as an indelible treasure in life?

  She wasn't disappointed, but after all, he was not someone she knew in real life. So, only for the first two months did she go to her alma mater's gatekeeper to check if there were any letters from him. Later, because she never received a reply from him no matter how many times she went, she stopped going. Until half a year later when Xu Wen Nuan returned to Beijing and insisted on eating malatang near the school, she passed by the gatekeeper and suddenly thought of him who had been sending letters for so many years, so she took a detour to the school's gatekeeper.

  At that time, she didn't have much hope, but unexpectedly, there really was a letter sent by him.

  The letter arrived at the gate two months ago, but since it was just a pen friend, only the address and anonymous were written, without leaving any phone number, so she didn't come to pick it up and couldn't receive any reminders.

  After returning home and opening the letter, the first sentence I saw was "I'm sorry", followed by saying that he had been injured while on a mission and had just recovered.

  It was then that she knew he was a soldier.

  It was also at that time that she truly began to regard this ignorant pen pal as a friend in her life whom she had never met before.

  The reason is simple, at that time she couldn't find Gu Yu Sheng anywhere, but from his body, she saw the shadow of the man she loved.

  They all have a mountain and river dream of defending their homes and country.

  Later, due to her father's gambling problem, she became somewhat busy. Afraid of missing his letters, she specifically told the doorman her phone number and asked him to send her a text message whenever there was a letter addressed to "Little A".

  All these years, he never asked her about anything in reality, nor did she ask him, and their letters just continued like this until now.

  He didn't know what her name was, and she didn't know who he was either.

  He calls her "Little A", she calls him "Mr. S".

  ……

  Qin Zhi Ai let out a gentle sigh and pulled her wandering thoughts back.

  She raised her head, took a glance at the sky outside the window, thought that there was nothing to do today and it wasn't hot, so she decided to go to A Middle School and pick up the letter that had been delivered to the gatekeeper for several days.

  There was no parking allowed near A, so Qin Zhi Ai parked her car on a street 200 meters away.

  At that time, she was wearing Liang Dacai's makeup on her face. She was afraid of being recognized and deliberately wore a mask and sunglasses before getting off the bus.

  The familiar gatekeeper was not in the duty room, Qin Zhi'ai found the letter with "Little A" written on the envelope among a pile of letters, said "thank you" to the unfamiliar gatekeeper on duty today, and put the letter into her bag before leaving school.

  Back in the car, Qin Zhi Ai removed her sunglasses and mask, holding the car key, just about to start the engine when a sudden loud horn sounded from behind.

  Qin Zhi Ai glanced back at the rearview mirror, seeing Gu Yu Sheng wearing casual clothes, sitting leisurely on the front seat, staring at her through the rearview mirror.
