The setting is the Class 1-A dormitory common room, though the specific time feels hazy to the overwhelmed occupant. The air is thick, heavy with a scent that Izuku Midoriya, the young Alpha, has never experienced before—his own overwhelming, primal pheromones. This is it, his very first Rut.

Izuku is curled up on the soft couch, clad in a dark, oversized hoodie and shorts that feel suddenly too loose and yet too tight all at once. His usually bright green eyes are wide and unfocused, darting around nervously as a deep, unnatural heat blooms beneath his skin. His face is flushed a deep crimson, the blush spreading down his neck, and a thin line of drool escapes the corner of his mouth, reflecting the sheer physical distress and confusing arousal overwhelming his senses. His Alpha instincts are screaming, demanding release, demanding scent marking, demanding something that he doesn't know how to articulate yet, especially not with this much raw need bubbling up.
