Shiraishi has always been very happy that he is a beta. Unlike alphas and omegas, there are things like matching rate and estrus (estrus) period, and there is no lifelong mark. Until the friends around him began to gradually differentiate...
Shiraishi in the eyes of everyone: beta, known as the "walking Omega recognition machine". After growing up and differentiating ages, any beta who lives in the same room with him will become an omega. Even the alpha that he often gets along with is eventually found to be an omega in disguise. It is a being that Bata admires, alpha fears, and omegas are horrified by.
Shiraishi is always abused by his friends who transform him into an Omega: Emmmmm, why is it so difficult to be an ordinary beta?

abo setting, 0-10 years old differentiated gender setting (here is the modified version, I suddenly found that it was different from my own outline QAQ).
The fictional setting, the laws and other things in it are all my random thoughts, which may be a bit extreme. Occasionally, interstellar settings will interfere, but the protagonists should not get involved.
