But he doesn't know that Hyeondo will be replaced once Hyeonso is back
I think he'll notice pretty fast. Bc only hyeondo can sooth Yisak's unstable pheromones. And the twin maybe has an opposite bitchy personality
he’ll for sure notice if he’s replaced. his brother and family is kinda dumb like i get omegaverses aren’t real, but even a dumbass could understand that pheromones r very distinct and that yisak would notice the switch up from their pheromones
100%. yisak is also very familiar with the mc’s pheromones and im sure its very distinct to that of his brother since he’s an actual dominant omega
yisak may be a little dumb but we all know he’s not that dumb to know if hyeondeo is actually replaced
