Two Hundred Years Later, We Became Aliens

It took humanity two hundred years to cross twelve light-years and bring two worlds face to face.

Then they discovered that their former compatriots had become the most familiar strangers.

Before war broke out, Earth historian Lin Chuan arrived on a colony world, where he joined scientist Kuang Shiyu to investigate the histories of the two worlds over the past two hundred years.

They wanted to know exactly when humanity had begun to drift apart.

But when they opened those long-sealed archives, the so-called betrayal planned long in advance, the conspiracy hidden behind history, turned out to be nothing more than a reply that arrived twelve years late, a disaster that could not wait for approval from the homeworld, and a group of ordinary people who had to decide where their next meal would come from before their plea for help could reach Earth.

Twelve light-years was too far.

So far that by the time the words "We'll come save you" arrived, the disaster was already over.

Later, a wormhole opened.

Twelve light-years became a matter of seconds.

Lin Chuan and Kuang Shiyu had thought that as long as people could speak face to face, the misunderstandings that had taken two hundred years to form could eventually be cleared up.

Until they discovered that...

Humanity could not become compatriots again simply by standing close enough.
