What’s Up with the Alphas at Your Police Academy?

Yueshui Huang is an unremarkable prospective police academy student about to take an exam. He wakes up one morning to find that the whole world has secretly gained a new setting behind his back. After being overwhelmed by a strange smell from the roadside, the young man grumbles as he opens a certain search engine and looks up "What are alpha, omega, and beta?" And so, a new world opens up before him. Yueshui Huang is deeply shocked. ...Wait, it's one thing for three new genders to show up out of nowhere, but what the hell are pheromones? Are they some kind of human-shaped aphrodisiac? Although the young man has a hard time adjusting to his new worldview, along with the changed world comes an extra set of memories. The outline he just opened is already memorized word for word, and his skills in sniping, bomb disposal, and disguise are climbing at an incredible rate, soon rivaling those of active-duty officers. Yueshui Huang: ...Nice. Although this bundle of memories comes with all sorts of nonsense, like the gruesome deaths of several handsome men, Yueshui Huang stays calm. He treats it like a tearjerker scene from a horror movie and doesn't take it to heart at all. Until he sees those five faces at the entrance exam. Yueshui Huang's pupils shake with shock. Shit, should he go say hi? Something like, "Hey, handsome. I dreamed last night that you were gone. Did you kill yourself?" Help, quick question: I'm an omega who keeps dreaming about my high-quality alpha classmates every day, and they keep pestering me every day too. What should I do? Please answer ASAP! Best answer: Hey there, we recommend you just marry them. Yueshui Huang: ? But there's more than one? Best answer: Isn't that even better? Yueshui Huang: ? You can think of this as an if-side story, not closely connected to the previous story. I've just been craving ABO lately, so I'm writing this for fun. A harem of men, melodramatic plot, ridiculous indulgence, and expertly out-of-character writing. The protagonist is an unconventional omega: he can fight, curse, and be a pain, and he flirts without realizing it. He's a certain kind of straight omega. (Meaning he has no awareness of alpha-omega dynamics and casually acts like a flirt.) (?) In this timeline, he's an upright police officer. The dreams are of the disastrous ending in the first timeline, where he was a true villain and everyone got a bad ending :) No one-on-one romance, no picking a love interest. Alpha-omega brotherly affection, you know what that means. The ending is only implied (yeah). #TheSharedSurnameIsACoincidence!ItIsNotASecretSetting!! #Nothing in this story is connected to reality.
