I think Byul will be an ALPHA because dojin's family blood are too strong and it's really possible that he is an Dominant alpha(づ ̄ ³ ̄)づ.
Look at the situation of dojin's family, they're all dominant alpha and they don't even have an omega even though their mom is an Omega(〜 ̄△ ̄)〜 while Hyesung's side is his father is an ALPHA and his mother is an omega right? So the blood that has the most is an DOMINANT ALPHA BLOOD
WDYM THE END HAAAA????!!!!!!!
