Bridge engineer Jiang Sui uses formulas and concrete to build love, fearing that everything will get out of control. Freelance photographer Sen Yu uses his lens to chase light and yearn for all the unknown.
They have known each other for ten years because of a band-aid. When Sen Yu was injured while filming, Jiang Sui's safe world that he had clung to for twenty years was completely shattered. Next to the unsolvable "Seventh Node" problem in the engineering log, he bowed to fear for the first time: "It's gravity."
This is a battle between guardianship and flight. They must find a way to love each other: not lock each other into a safe, but become each other's strongest support in a dangerous world.
The so-called love is to become the seventh node in the other person's life that is willing to be marked.
Intent: In an era when everything can be calculated, love is the last and only force majeure.
