Adel's manga / #Omegaverse(2)

OMG I LOVE THIS MANWHA. This will be my favorite o(≧∀≦)o And when reading this I thought jinwoo was older than colton (˵ ¬ᴗ¬˵)

This made me confused.Is the omega a uke or seme( ╹ -╹)? But if he’s a seme this would be my first omgaverse where the seme is an omega (˶˃̶ ᵕ ˂̶˶)
