No, this author is always exploring genres in her omegaverse series.
First couple: Alpha x omega (both male)
2nd couple: Alpha x beta ( both male)
3rd couple: beta x omega (both male)
4th couple: Alpha (F) x omega ( M)
5th couple: Alpha x Alpha (both male) Siwoo and Byul
If we are lucky we can have the 6th couple: Alpha x omega ( both female) Soyi and Bin
If I remember correctly, isn’t Soyi a beta? So they would be beta x omega
Soyi is an alpha
Oh yeah, author is completing the omegaverse genre (▰˘◡˘▰)
Im starting to speculate that maybe byul is like his mom, presented alpha at first but then really an omega. Or that im just hoping byul and siwoo will have a baby of their own (づ￣ ³￣)づ
