A Beta Sends the ABO Powerhouses into a Love Rival Showdown

(Main story complete) Jian Momo transmigrates into an ABO novel. In this world where pheromones reign supreme, she has no glands and is therefore deemed the least desirable kind of Beta. Luckily, the System's mission sounds simple enough: Help the male lead defeat three antagonists of different ABO genders, help him marry the princess, and then she can go home once the plot is complete. At first, these top predators, including the male lead, won't even spare her a glance. Jian Momo is happy to keep a low profile and just wants to stay alive and get out. But then... Jian Momo realizes that these people seem to have gone crazy. The unruly Alpha pins her against the wall: “I once thought pheromones were everything. Now I see I was wrong.” The Beta, whose wealth rivals an empire, spends a fortune on her: “Betas belong together. It's only natural.” The beautiful, sickly-sweet Omega presses a dagger to his own heart: “So what if I'm an Omega? Does that mean I'm not a man?” The male lead, who was supposed to marry the princess, raises his blood-red eyes, looking every bit like a villain. “So from beginning to end, you were only using me?” He toys with the trinket in the golden cage and says lightly: “Go on, pick one yourself.” Having no glands and being impossible to mark means she can never belong to anyone completely. That drives these accustomed-to-control highborns over the edge. They despise her unconquerable imperfection, yet at the same time, she awakens something primal and savage in them. If pheromones won't work, then they'll use the most instinctive means of all, imprinting their presence on her as tears burst from her eyes beneath their rough thrusts. Content warnings: • This isn't a wish-fulfillment story. It features coercive possessiveness, a father-and-son rivalry, a womanizer who reforms, and one male lead who dies. The plot includes a minor male Alpha attempting and failing to mark a male Omega during a heat. (But none of the male leads have ever been attracted to male characters, including Jin Lan! They have never been attracted to one another!) • There is no single male lead. Most of the male leads are villains, each flawed in their own way. • The heroine is focused on completing her mission. She isn't perfect and will make mistakes. (These are the content warnings I can think of.) Theme: Let the light shine on all, without distinction
