Struggling to Survive in an Interstellar ABO World

Female B, male A, 1v1. The heroine is reborn in the apocalypse, in a world of interstellar military academies.

This is my first time writing, and the setting and worldbuilding are quite expansive, so things may be a little confusing early on. Please bear with me!

The forums are in an uproar: Breaking news! The Third Prince signed up for Shen the Tiger’s class?! Your Highness, protect that handsome face!

Combat training ground: Her moves are ruthless, swift as a specter; he presses her relentlessly, his endurance unyielding. Every clash is both a test and a contest.

He presses her for an answer: “Why did you save me on the junk planet? Who are you?”

She stays on guard: “Your Highness, focus on training. Skip class and you lose points.”

But the conspiracy on the junk planet never truly disappeared. Once again, a dark hand reaches for Shang Shixu, coveting the pure bloodline of the imperial family. Will Shen Que step forward to save him again this time? How will her shattered past collide with the royal fate he bears, amid this iron-fisted military academy and the vast sea of stars? When survival and truth become each other’s only salvation, can the rose blooming in the abyss truly blossom under the protection of the Empire’s crown prince?
