@IMayBeWrong i didn't this of it that way but you may be onto something! Although they are both alphas so they don't get affected by pheromones (unlike omegas) but one alpha senses another's scent so that they know if the territory (an omega) is marked. I wonder whether maybe Buyl's pheromones affect Siwoo because Siwoo clearly likes Buyl? Idk we'll see ✨
