Qing Yan, a fishing cage maintenance worker in a seaside town, used his hands to repair the net ropes eroded by time and tide, but he could not repair the lover who chose to escape when the seafood collapsed. Three years later, he returned to this sea, and she became the person who knew the ropes best in this fishing ground. She taught the knot how to withstand the tension, but never learned how to bear the absence of a person. This is a story about repairing skills and soul - some knots can be untied, some ropes can be connected, and some can be left. No matter how densely patched, there are still gaps for ventilation.
