According to some spoilers I read from long ago(I may be wrong or I may be getting it mixed up with a different one).

SPOILER:
He is a beta, he doesn’t switch into an omega but he does however end up getting pregnant due to some fairy bs happening idk really
Spoilers:
Don't worry MC won't become an omega but he becomes pregnant and gives birth because he wanted to have children as he is blessed by the Fairy King and has fairy blood.
...but I really hope Renato doesn't magically become an omega. I quite like the dynamic between beta/omega and alpha/beta. With the added bit of angst about the other party potentially preferring omega's/alpha's over beta's.
