A Plain Beta's All-Alpha Shura Field

[Cyberpunk setting, complete!] New story: My Obsessive Dream Boyfriend’s Self-Cultivation [Apocalypse] is updating now. Coming soon: After the Villainous Alpha Becomes a Succubus [Blurb] Zhu Yu is an utterly ordinary beta police officer in Kowloon Walled City. She works diligently every day, hoping to save enough for retirement so she can quit and leave. Her useless father botches a deal, and to pay off his debt, she is handed over to the Shen family and engaged to one of them. Two days later, Zhu Yu goes to meet her fiancé. Her fiancé, Shen Yexuan, is a top-tier alpha. He’s handsome, and unlike her sour-faced superiors, he always seems carefree and never stops making suggestive remarks. They keep out of each other’s way. Shen Yexuan sells equipment, while Zhu Yu goes to work and patrols. Sometimes they run into each other, and Zhu Yu helps him deal with robbers. Shen Yexuan’s presence doesn’t rock Zhu Yu’s life very much. At most, she has to put up with him a little during his rut. The first time, he bit and nipped at her, dropping his usual laid-back manner. His face flushed as he anxiously asked her, "Why can’t I mark you?" Zhu Yu: "Could it be... that I’m a beta?" Shen Yexuan has an omega younger brother, Shen Baijue. Shen Yexuan’s older sister gives Zhu Yu two million to protect Shen Baijue until he graduates, promising to pay her another five million afterward. Seven million is more than Zhu Yu could earn in decades, even if she never ate or drank. She happily agrees. Shen Baijue’s pheromones have a special effect that intensifies alphas’ desires, bringing trouble his way. Zhu Yu deals with each problem in turn, taking good care of her money-maker. Shen Baijue misunderstands her kindness and repeatedly invites her over during his heat. Shen Baijue is an omega. Male omegas are... like chili peppers hanging from a tree. Besides, she’s a female beta, with nothing down there. Everyone around them, including Shen Yexuan, can tell that Shen Baijue has feelings for Zhu Yu. But what can a male omega and a female beta do together? Zhu Yu thinks so too. So whenever Shen Yexuan’s rut comes early or lasts longer than expected, and he grows strangely tender in the dark, it never crosses her mind that anything else might be going on. Zhu Yu’s ex-boyfriend, Zhong Lizhi, is a police officer like her. Shen Yexuan: "Oh, he’s just her ex-husband." Shen Baijue: "A boring man who’s always stern with my sister. She doesn’t like him, so he’s no threat." Zhong Lizhi: "I was her first love." Shen Yexuan: "Hmph, she’s my wife." Shen Baijue: (cocks gun) (raises gun) (takes aim) Please note: 1. Characters’ views do not represent the author’s. This is a fictional setting, so please don’t compare it to reality. 2. The female lead has prior experience, while the male leads do not. Fierce competition among the men. All the male leads are hopeless romantics, and the female lead is known as the succubus of Kowloon Walled City (just kidding). 3. Cyberpunk setting. The balance of plot to romance is 3:7. 4. More may be added later. Theme: Love life.
