Three hundred years after the end of the world, Atlantis is two thousand meters deep and is the last ark of mankind. Survivors on the surface struggle in a poisoned world, harboring a grudge against a deep-sea paradise.
Lynn, an elite New Eden agent, disguised as a geologist and infiltrated Atlantis. Eric, a core member of the Supreme Council, is cold and rational. He sees through the disguise but chooses to remain silent.
When Linn discovered that the ancient energy "Heart of Poseidon" was hidden underground in Atlantis, and when New Eden issued an ultimatum to seize it, the two of them had to choose between their stance and their emotions.
Should they protect their respective civilizations, or betray everything and look for a third possibility before destruction?
Two thousand meters deep in the sea, a forbidden love intertwined with love and hate is taking place.
Intent: In the face of the ultimate proposition of civilization's survival, personal emotions are as small as dust, but as hot as flames. Core idea: When the boundaries between "us" and "them" become blurred in the face of survival, is love the final salvation or a deadly poison?
