In the coldest end of the world, love is the only source of warmth.
When the world froze at minus 60 degrees, human beings huddled in the last "ark" to survive. Shen Jian, the rational security commander, was ordered to hunt down a technician who violated the rules, but unexpectedly uncovered a truth that had been buried for seven years-under the ice, the "cold" itself created by humans was imprisoned.
Technician Jiang Shuo, an idealist who cultivates spring in the laboratory, holds the key that his parents gave their lives for: a strain that can talk to underground existence. He believed understanding was more powerful than fear, even if the world thought he was committing suicide.
From pursuit to escape, from hostility to dependence, two completely different souls are torn apart and stitched together in a desperate situation. Shen Jian learned to use data to calculate the "survival rate of love", and Jiang Shuo learned to plant hope on the ice sheet.
Humanity's answer will determine the outcome of civilization.
Meanwhile, at the heart of power, another silent war is taking place. Shen Jian's brother Shen Heng, a secretary-general who quantified feelings as a political bargaining chip, was forced to enter into a contracted marriage with Lin Che, an orphan from an artistic family. He thought it was just a deal until he discovered the ever-smiling "little sun" with antidepressants hidden in his pocket and silently collapsed in the bathroom at midnight.
When the agreement expires, when the truth emerges, when spring begins to grow quietly on the edge of the ice sheet——
Two couples who start in the most unlikely of places must make a choice:
Should we continue to live in carefully calculated lies, or should we bravely move towards the truth where we may freeze to death or be reborn?
