At first seme was totally treating mc not as a "human" but as a mere omega, calling him "an omega who wants to be an alpha", just because he's a top. Insinuating that omegas only Botton and an alpha has to top, also calling him "omega" instead of his name.
Then suddenly he says that second geners don't matter and they are all human being's and that "Aoi is Aoi"
It didn't make sense to me
By the summary I get that... Seme's a pedo?
He explained why he only pick high school looking boys on chapter 4 I think.. there's a panel when the uke's first regular customer came and reserved uke then sa seme ask for another boy.. he said that he thought he really was into high schoolers boys but then when it's not the uke he was not interested at all..
This is really, really, really infuriating, but REALLY.
Gosh save yourself the anger my gosh...
