In a future where the elixir of life blurs the boundaries between life and death, as one of the producers of the elixir of life, Yamazaki Sota is a highly respected human opinion leader and the most majestic figure in Erica's entire childhood. She once called him "Cang Tai". He was her father's best friend and the embodiment of eternal reliability and admiration in her eyes.
However, the gospel of technology has not brought permanent peace. When the shadow of factional wars triggered by organizations that are enemies of openness and monopoly envelopes the earth, and when the ultimate nuclear explosion lights up the night sky and turns the homeland into scorched earth, the fragments of human civilization are forced to migrate to large space stations orbiting the earth. On this isolated metal island called "Space Station 2", the ethics and order of the old world are crumbling in the face of survival.
The former girl has grown into a top-notch low-level engineer of the site management system, using technology to maintain the operation of this isolated island. Yamazaki, on the other hand, stands at the center of a larger whirlpool, looking for a way forward for the remaining fire of mankind. They are no longer the elders and juniors, but interdependent living beings in troubled times. The shared destruction and rebirth turned the dependence rooted in looking up into the end point of finding the meaning of life.
On the cold steel track called life, in front of the porthole overlooking the devastated earth, spanning nearly half a century of distance and long memories, they finally discovered that the emotion that began with looking up had already settled into an emotion that they couldn't let go of in the ups and downs of fate.
In the magnificent new era of fleets, when two souls influence each other, the ripple effect determines their willingness to transcend time dimensions and ultimately find each other's destination.
Intention: Looking for self-interpretation of life and death in confusion, so the love that emerges sees through his indestructible disguise. She gently took over the burden of years on his shoulders, redeemed each other, and became his eternal harbor.
