I Rose to Wealth and Power While Fleeing an Arranged Marriage

As an orphan from a remote imperial star system, she had neither a bloodline nor a family background to speak of, and not even a proper name.

Her goal in life was to complete more missions, earn a little money, and open a shop with the person she loved, selling the low-grade mechs she designed herself.

Then she found out her fiance was the Crown Prince of the Empire, and everything changed.

"She escaped, crossing the asteroid belt and traveling through star systems, wandering the outskirts of nebulae. She witnessed the death of stars and the birth of life, the steadfast devotion of four 'suns' orbiting one another, and humanity's battles and sacrifices as it ventured into the depths of the universe. Perhaps it was there that she saw the light in her own hands... And so, one day, she finally understood that even if she had nothing, her dreams could still be more vast than the starry sky.
