Oh. This story is in an Omega-verse setting. Where people are either Alphas, Betas, or Omegas. There is usually discrimination against Omegas and high-regard for Alphas.
Male omegas are capable of conception and birth. They are one of the rarest ones, usually. :) There are also concepts in the omega-verse where they have a 'heat' period where the omega is fertile and send out a lot of pheromones. Attracting any nearby alpha. Most uses suppressants to restrain/ prevent their 'heat' from coming. And using those suppressants, they try to pass off as betas.
my tongue almost got twisted reading Hikari Gibberish (≧∀≦)but still what is this alpha omega relation and how can misaki have a baby (⊙…⊙ ) please can anybody solve this case?
