Honkai: Star Rail: An Ordinary Person with Maxed-Out Affection?!

When the world is fake, hope is fake, and everything beautiful is fake, with only despair being real, what would you do?

This is a Honkai: Star Rail world with no correct timeline. Everything in this world follows the worst possible timeline.

The Great Herta's head was stolen, and the Iron Curtain merged with it. In the end, the world fell under the calculations of Erudition.

The Astral Express's journey came to an end. Welt, the savior from another world, eventually vanished into a black hole, while the Astral Express Crew perished together in the flames of the Blazing Wind.

Memory awakened once more, divine might covered the cosmos, and everything froze in the instant before death, at the moment of eternal death.

…

Everything here is fake, but love alone is real. So, Yusheng... how will you spend the rest of your life?

Will you watch helplessly as the fake becomes real and beauty turns to destruction?

Or...

Will you steal that tiny spark of hope, the [kindling], for the sake of a genuine future?

Yusheng, oh Yusheng... will you become Yusheng, or [Prometheus]?

“I don't know, but I'll keep running until I reach the right answer. A wild dog doesn't need a gravestone. It can just run until it rots along the road.”

P.S. A very slow burn, with angst in the story and a sweet ending.
