At the beginning of the birth of the universe, a soul named "Source" was split into "light" and "shadow" because of its resistance to homogenization, and was punished into endless reincarnation. From then on, the two halves of the soul traveled across the stars and experienced seven thousand reincarnations - sometimes forgetting each other on alien battlefields, sometimes embracing each other in deep sea ruins, but always being pulled by invisible gravity.
On the ocean-covered planet Celeste, underwater architect Leah and geologist Aiden meet. The moment of contact awakens the memory of quantum entanglement: they are twin flowers in the desert, mortal enemies in the space station, strangers in the mechanical city... And every time they meet again, they are hunted by mysterious forces. When the crisis in the deep sea reveals the shocking truth about the planet, the two discover that the entire universe is actually a testing ground for advanced civilizations, and their souls are the only variables that can escape.
In order to fight against the system's harvest, Leah and Aiden choose the third most dangerous path: carve each other's light traces into the bottom of time and space, and let love become the law of reversing entropy. In the end, the light of the binary star system wrote a love letter in the vacuum, and thousands of civilizations heard the original resonance of the universe - "It is better to forget each other in the rivers and lakes than to help each other in the sea of stars"**.
Intention: The universe will eventually disappear, but love will last forever.
