Alphas Are Forbidden from Releasing Pheromones

[Complete. Any further updates are for proofreading.] Before her secondary gender manifested at eighteen, Ni Jian was certain she was an alpha, and she worked hard to prove it. In school, she excelled among her peers in shooting, combat, academics, and all the other courses. One day, she came across an injured beta who was barely clinging to life. Out of a sense of justice and a desire to stand up for the weak, she took him home. Once cleaned up, the beta turned out to be reassuringly handsome. He was also sweet and well-behaved, but he couldn't remember who he was. She took him on as her sidekick and thumped her chest, solemnly promising she wouldn't let anyone bully him. Until Ni Jian saw him take down five alpha assassins all by himself. The bloodstained man walked toward her. His powerful pheromones overwhelmed her, leaving her unable to move. She could only let him bend down and sniff the gland at the back of her neck. "You smell so good." "I really want to... mark you." She was on the verge of tears. This was not the outcome she wanted. - Only later did Ni Jian learn the truth. The "beta" she'd picked up was Wei Liu, heir to the most powerful family in the Federation. He was a born alpha, with top-tier abilities and genes. The pheromones he gave off had a fatal allure for an omega like her. And she hated the pheromones of every alpha, without exception. She thought they would never cross paths again. Then, during a mission, they were accidentally trapped in a moving train car. That familiar scent. His overpowering pheromones pressed closer inch by inch, surrounding and besieging her from all sides until her legs went weak and she could barely stand. A streak of white light flashed by, illuminating the man's handsome, sharply chiseled face. Wei Liu pressed his fingertips to the back of her neck, which was growing warm, and fixed his gaze on her. "Do you need my help, like before?" Ni Jian couldn't answer. All she wanted to say was: Stop releasing your pheromones at me! She really can't take it :) - Wei Liu spent the first half of his life living by the sword, hiding his true intentions and enduring everything, all for revenge. In countless midnight dreams, he would remember someone telling him, "I hope you'll stay safe and sound from now on. I'll call you Ping An." When he was trapped in desperate situations, the memory of her voice was the only thing that helped him fight his way out. Later, she stood before him again, and his pheromones went completely out of control. Justice-obsessed, straight-laced omega × wolf in sheep's clothing, sly alpha ■ 1v1, happy ending. They are each other's first in every way, and their feelings for each other are incredibly strong. ■ ABO setting. You don't need to know anything about it. This is a self-indulgent, sugary, Mary Sue romance. ■ The technology is probably a few decades in the future, with a tiny bit of sci-fi. Lots of original worldbuilding, so don't overthink it.
