The Empire's Rose [ABO]

[1] In Imperial Year 239, it had been thirty years since naturally differentiated Omegas went extinct. Some Betas were artificially differentiated into Omegas with monotonous pheromones, capable only of bearing Alphas and Betas. For the sake of her family's honor, Si Ting was forced to become one of them. Just as she was losing hope for her future, she suddenly realized something was wrong. ...Why were all those Alphas looking at her so hungrily?! She had a unique "scent," the sweet pheromones said to be found only in those who differentiated naturally. To protect herself, she got hold of a multifunctional bionic robot that was said to satisfy her needs while suppressing her scent. [2] Si Yan, the empire's supreme commander, was gravely injured in a war and became a vegetable. His consciousness, however, attached itself to a certain bionic robot. The moment he opened his eyes, he saw his younger sister, whom he had strictly disciplined but never been close to, holding him with flushed cheeks. Si Yan: ... Oh, no. The day before he fell into a coma, he'd learned they weren't biological siblings. Now, as a robot who had to obey her, he had no choice but to satisfy her through the pain and abandon of her heat. He thought she'd ultimately been sacrificed by her family and forced to undergo artificial differentiation. That was until he saw Alphas going crazy over her, until his consciousness returned to his body and he awoke from his coma, personally catching the unusual, intoxicating scent. "Brother." When she welcomed him home in triumph, she wore a proper, conservative long dress and smiled with polite restraint. She was utterly different from how she was on those nights. He took off his military cap and gloves, suppressing his Alpha instinct to claim her, and smiled at her faintly.
