ITS ONLY THREE CHAPTERS, CALM DOWN YR QUESTIONS WILL BE ANSWER IN DUE TIMEಠ∀ಠ
In his eyes, alphas are like the one having sex with his roommates and the one sexually harrasing him now (in the novel he even groped his ass). But Seo Jinhyuk is not like that, he's very polite and refined. His indifference is always emphasized in the novel. Asel can see that Jinhyuk doesn't see him like other alphas see omegas. Also in this omegaverse world setting it's normal for alpha or omega to use their pheromones to "converse" somewhat, like to show interest, friendliness, dislikes etc. Seo Jinhyuk is the only alpha he's ever met that hold his pheromone in, so much he didn't realize he was an alpha.
Also right now it's just a simple crush he could still give up on, it'll grow as Seo Jinhyuk keep doing kind things for him ╮(￣▽￣)╭
I really dont get the omega at all!!!! He's kinda like self deprecating and he knows how the world works... The story is telling us that he views the world in a pessimistic way due to his childhood... He sees alphas as alphas... So tell me why the story is telling me that the MC sees the ML different...u just got a tip... U just served him... Is it love at first sight? But u know how the world works so ure aware...so why is the ml an exception of your perspective...(╯°Д °)╯╧╧
