Boku No High Spec Kareshi-sama
The whole manga puts a twist on omegaverse! And the seme is right, why do omegas have to be bottoms; why can't they, too, be tops? Just because they can breed, doesn't mean they have the be the ones to be bred. Besides that, though, I love the execution of every joke in here. The manga doesn't even feel like it tried that hard to make it funny, it all just feels natural; like it's common sense, when it's obviously not. This just makes it more funny as time goes on, with the MC(omega) rejecting everything the uke(Alpha) see as normal. I mean, the scene where they first met was the most random and funniest shit I've ever read in the last two years. I can't get enough of this manga, and I love that fact that it's just breaking down walls and stereotypes. This is possible, no, this is the best fucking omegaverse manga I've ever read; I just love the light atmosphere it has.
