If you read carefully, I believe it actually says that he found out he was a recessive omega at 19. He hadn't had a heat though until that night with Felix (presumably he started taking meds as soon as he found out). Pretty sure he said somewhere that he's about 30, so he would have been 26 or so that night, but up until then he was uninterested in sexy times and being an omega in general.

Yes, i double checked that part too. Him saying he was 30.. thats only in the korean mahnwa.. the novel didnt have isaac mentioning he was 30 at the beach...
Some time ago i even went to to reply under author’s twitter asking about this 19/30 thing..... No response tho.. however, its likely that Isaac just lied about him being 30 something..

i don't think that's true tho. he mentioned in two places at least that it was his first ever heat cycle in the island. how could he find out he's an omega at 19 without having a heat cycle?? imo he was 29 at his first heat when he realized he's an omega, got pregnant and had benji. now he's probably 32-33 and felix is around the same age. i think it was just a mistake that they said 19 instead of 29...

Nah ur literally pushing this agenda when the original author and artist of this story clearly stated “ 19 “, youre NOT the author, they are LOL. The only discrepancy is of when isaac mentioned he was 30 in the mahnwa raws but in the novel he didnt say he was 30. At least go check the damn raws instead of yapping over here without no actual proof

You're the one pushing an agenda. Why would he have inhibitors on him that night on the island, if he didn't already know he was an omega? It clearly says he found out at 19, and he had his first heat on the island, not that those things occurred concurrently.
Leading a group of soldiers at 19 makes absolutely no sense at all ┑( ̄Д  ̄)┍ Its an omegaverse so I don't think the particulars of finding out really matter, but I assume as a 'recessive' omega he didn't have heats or the usual omega traits, and he probably found at at a regular check up or something ("uh hey, btw you know you got a uterus attached to your asshole?" ╮( ̄▽ ̄)╭ )
i'm very VERY sure that isaac's heat didn't hit him at 19, it was 29. is it a mistranslation? bc rn he's in his thirties, and he got his first heat four years ago. ain't no way four years ago he was 19 lmao
