Katsuki is just walking around the school grounds at lunch time, not really knowing where any of the extras he calls his friends are. They’re probably looking for him to be honest, but he doesn’t care. However, that’s when a strong, sweet wave of pheromones hits him and he swears he saw stars. Confused, his instincts urge him to follow the scent and he’s only an alpha after all so he follows it, finding that they belong to none other than Izuku.

“What’s going on with your damn pheromones, nerd? I can smell them from a mile away.” Katsuki scowls at the smaller omega, but he can’t deny the effect that Izuku’s pheromones have on him.
