Just as the car was about to leave, Mr. Gu hadn't left yet... The butler was somewhat surprised and couldn't help but stare blankly for a moment before speaking up: "Mr. Gu?"

  Gu Yu Sheng was lost in his own thoughts, unaware of what he was thinking about, and remained still for a long time with the cigarette clenched between his fingers.

  Just as Guan's family thought that Mr. Gu would not care about himself, the man turned his head and looked at her. He didn't speak, but first handed the cigarette to his mouth, took a deep breath, and stared at the stairs behind Guan's house for a while before speaking: "How is she?"

  "The young lady took a painkiller and has fallen asleep." The housekeeper knew who the "she" in Gu Yusheng's mouth referred to, and answered honestly.

  Gu Yu said "oh" and continued staring at the stairs in silence.

  His face was expressionless, with occasional wisps of smoke drifting across his cheeks, making his elegant and handsome features emit a faintly mysterious beauty.

  When the cigarette had burned down to its end, Gu Yu Sheng slightly bent his body and extinguished the butt in the ashtray on the windowsill before walking towards where the butler was standing.

  For a moment, the butler thought Gu Yu Sheng was going upstairs, but when he reached the intersection of the corridor leading to the entrance and the stairs, he stopped.

  He stood still for a moment, left a sentence "take care of her" to the butler, then stepped forward, walked towards the entrance, changed his shoes, and pushed open the door without any delay, and went out.

  After about a minute, the sound of the car starting came from the garage, first getting louder and then smaller, until finally nothing could be heard.

  The second day of her period, Qin Zhi Ai stayed at home and rested for a whole day.

  On the third day, Qin Zhi'ai fully recovered as usual.

  It was cool today because of the rain last night.

  In the morning, Qin Zhi Ai went to the garden and picked a big bunch of fresh flowers that were about to bloom. She filled all the vases in her home with the fresh flowers.

  After lunch, she rested for half an hour and woke up thinking that she had been using Liang Doukou's mobile phone number for a while, and hadn't checked her own phone's messages for several days. So, she took out an old-looking phone from the inner pocket of her bag, turned it on, and after a while, there was a series of beeping sounds. After about five minutes, the phone returned to normal. Qin Zhi Ai looked at it and saw that her mother had made a call, her brother had sent several messages, and the rest were weather forecasts from 10086. The last message was from the courier company reminding her that there was a package waiting for her at the gate of building A, please pick it up yourself.

  ……

  A was the high school where Qin Zhi'ai and Gu Yu Sheng studied together.

  As soon as she saw going to the gatekeeper's place to pick up the express delivery, Qin Zhi'ai knew that it was a reply letter from that person.

  It's probably hard to believe that in this era of WeChat and QQ, no one uses letters as a way of communication anymore.
