My theory is that Siwoo is an Omega, why? I just re-read this and paid close attention and not once was it ever confirmed that Siwoo is an Alpha, people just assume from his physique. I also noticed when Byul wanted to smoke Siwoo's cigarettes he snatched it away in a panic and Byul even pointed out the cigarettes had quite a smell to them. I read in another series that sometimes Omegas can use cigarettes to mask their Omega scent, which would add up here. Also I have read in other stories before (rarely) if an Omega is put on suppressants early enough, their second characteristics won't form and so they can pass more as a Beta or Alpha. Also with what just happened in the most recent chapter, it seems like Siwoo's body reacted painfully to Byul's angry pheromones, which usually Alphas aren't too affected by but it definitely can affect Omegas. This is just a theory though, guess we will see moving forward.
maybe byul is one of those dominant alpha types (which wouldnt be a shock since dojin's family is full of them) and siwoo is just a regular alpha hence why he reacted to byul's pheromones
