Ruan Xi is a deep well waterstop deformation surveyor of the Water Group. This job sounds scary, but to put it bluntly, it involves hanging a steel cable down a hundred-meter-deep well every two days, and using an ultrasonic instrument to shine on the circle of dark rubber - if the compression is too tight, the well wall will crack; if the compression is too loose, sediment will seep in; when the temperature changes, the rubber will tire. She deals with deformation data every day, and knows better than anyone else that between people, if the pressure is too little, it will leak, and if the pressure is too much, it will collapse.
Ten years ago, she was a poor girl who couldn't even pay her tuition. The brother next door, Anyu, clutched two tickets and wanted to take her away. She shook his hand away and said, "Go away and leave me alone." She knew that if he took her, a person in a mud pit, he would never be able to fly far in his life.
Ten years later, the turbidity in Well No. 3 In the city exploded. She went down to inspect the well and found the secret code he had carved when he was a teenager on the worn fragments of the water stop. After climbing out of the well, the new project supervisor stood in the crowd, pushed up his glasses, and called her "Gong Ruan."
The boy she pushed away ten years ago is now back with a complete improvement plan to build the well. But the old debt of her father's tampering with hydrology reports and cutting corners is still lingering. The walls of a well can be mended, but can the human heart? This time, will she continue to tighten her grip and squeeze her lover to pieces, or will she let go and let the mud and sand fall?
