Honkai: Star Rail: The Aeon Who Loves Stealing Other People's Partners

[Single heroine: Jingliu + feel-good power fantasy + redemption + nearly invincible protagonist + daily life + transmigration + System + semi-alternate timeline + some inexplicable elements]

Once, a very, very long time ago.

It was said that in that era of declining magic, there had once been a sole true god in the world.

That god was [Fate]...

In that era, people once worshipped Fate, betrayed Fate, and waged war against Fate...

After living for countless eons, as memories gradually faded into the distance, Fate often wondered: Why did life fall asleep, and why did it exist?

Was everything Fate had stood by truly meaningful?

As the god who ruled over destiny, Fate had instead taken a path directly opposed to it...

Born of predestination and the end, Fate nevertheless sought to change the destiny that had already been decided. Fate believed destiny should mean freedom, not a shackle and a source of suffering for the people. So Fate descended into the abyss, seeking to end destiny's injustice and show the world that fate could be changed...

In time, Fate became the people's savior. Anyone afflicted by an unfortunate destiny would find redemption at Fate's hands, and a future of infinite possibilities awaited them.

But as the ages passed and Fate lived for countless eons, Fate witnessed too much human cruelty and endured too many betrayals. At last, a trace of doubt crept in:

Perhaps destiny had always been ordained to end in oblivion. Then what was the meaning of my existence?

And so, as memories continued to fade, [Fate] too began to suffer and sink into despair...

It seemed everything had returned to where it began...
