There are more healthy abo stories out there http://www.mangago.zone/home/mangalist/334330/
Nope. Omegas are still looked down on in this society. You don't remember why Doyun started to dislike Taehan? Because it was automatic to believe that alphas are stronger than omegas. Also, a mother being happy about her son producing rape soliciting pheromones while not having to worry about them herself makes me want to call the FBI on her. Thx.
You are applying rules from different stories to this one - Doyun disliked Taehan from the very beginning – there are no indicators that his dislike stems from the fact that Omegas are looked down on, and the only reason why Alphas think of them as “weak” seems to be because most Omegas are of delicate build, it's about physical strength, therefore justified. That being said, if you have interpreted something differently, then please point me to the chapter in question, maybe I missed something worth knowing.
I'm quite impressed, so far this is the healthiest ABO story I've seen, it seems that Omegas aren't oppressed or looked down on, everyone is impressed when they work hard, they are treated pretty well, not to mention that Doyun is playing an Alpha like an instrument, and said Alpha goes along with it. Although his family is uncomfortably invested in his life to the point that it's nigh creepy, at least his mother genuinely cares about him, is happy for him, and wants him to be healthy – I can imagine how relieved she must feel now that he's finally developing in the right way. You can compare it to a human child that doesn't hit puberty, it's a serious abnormality and a good reason to be concerned.
