Gyuha was taking medications to suppress his omega trait and it affects his body functions that's why he's tall and buffed. But there was one time that he took the wrong medicine which makes omega trait stronger with high percentage of being fertile. Then he forgot to take his actual medicine and had sex with Chayoung in his rut. So I don't think Gyuha has that natural lube that you're talking about.

1. Betas in this author’s universe do get wet.
2. You can see in chapter 16 that the MC gets wet after the ML gives him a blowjob.
3. Not sure if it’s mentioned in the manhwa, but the ML does notice that the MC tends to get wetter than other betas that he’s been with, but it doesn’t strike him as odd enough to make him think that he might be an omega.

- Gyuha had a surgery that altered his pheromones and basically masked most of his omega traits except his gay attraction that he thought was because he's an omega (even though there are technically female alphas)
- male betas in this universe canget wet but not as much as omega or chayoung is just a dumb alpha that wasn't socialized to know the details of other sexes, so chayoung took gyuha's words for granted when he pointed out gyuha got wet. Also they've been having a threesome with that twink beta so maybe male betas can get wet
- chayoung had always used lube instead of going in dry so gyuha always had a reason to chalk his juice of as "I already prepped" or "my body is just that sensitive, so I get wet that much even for a beta(see second point)"

I think the dumb alpha thing is more likely, I understand that every universe is different but betas have always been the same they’re the definition of “us” ie the “norm”. The author makes a point of male omegas still being with female alphas because two men still isn’t “normal “ so why would betas (male ones) naturally get wet. Doesn’t add up

“chayoung is just a dumb alpha that wasn't socialized to know the details of other sexes, so chayoung took gyuha's words for granted when he pointed out gyuha got wet.”
Except this scenario never happened. Gyuha never “explained” his wetness to the ML because betas getting wet is something that is known inside the story’s universe, so he never questioned it. When he notices that Gyuha gets wetter than other betas that he’s been with, we get this information in his internal monologue, it’s not a discussion between them.

“I understand that every universe is different”
Do you? Because I think you’re struggling to understand that this one is… I would suggest reading more omegaverse. Betas are not always strictly regular humans like irl. In some omegaverses, they can have alpha or omega traits. It just depends on the author. Like, this really isn’t that unique.

TBF intersex is a thing and I imagine it's way more common in omegaverse so there might be alpha-leaning betas, omega-leaning betas, and true betas but it was never mentioned in the manhwa (tho idk about the novel since some artists don't go strictly by the book)
Also, sexual organs aren't just for procreation, some anatomy variations can work as population control since ruts and heats give higher chance of mass pregnancy

Because the logic is dumb af if that’s the case here, why make it a taboo to have a male x male when all males are biologically created to accept other males? Like…if you’re going create a universe and be different I’m down for it but have some logic behind it. My original post wasn’t actually dissing this story either btw, I was stating how some mangas they don’t have betas who get wet and the alphas never realise the omega isn’t a beta so I was praising this one, However you’ve pointed out s flaw so now imma have to wait to see if this is just badly thought out and not as good as I originally thought.

I don't really read original story omegaverse unless I'm interested with the premise or the character design so I don't have any recs aside from ao3 fics
If betas getting wet isn't your vibe you can choose to ignore it, it's not that relevant till the end of the story (and we've come this far so it's funny if you'd drop this just for that )
I was always curious how an alpha wouldn’t know another man was an omega. Or even a beta due to the natural….juices? That happens but then this manga kinda gave me an insight- any man would instinctively use lube unless they were sure the body wouldn’t need it. Gay men and even some straight couples deffo need it so he just straight up lubed him up. Then ofc the author was also really good at covering the other loophole- taste. Author covered the texture part and so they were careful not to include the tongue lashing because I’m sorry….anyone would know the difference then between lube and natural. Even in fantasy so I’m glad this author actually showed that lol. Other mangas with similar tropes I just dropped because well…it’s dumb and you can’t mistake it for lube if it’s in a world without it anyway….thanks fofor reading my dumb af thoughts.
