Summary
The thought of Kacchan going into a rut while they are trapped in this cave together should be terrifying. Any unmated omega in their right mind would feel nothing but dread at the mere possibility of being at the whims of an instinct-drunk alpha.
Surprisingly… or maybe not that surprisingly at all, Izuku can only feel the tickle of anticipation in the pit of his stomach. Caged butterflies with their delicate wings teasing at the backlog of less than wholesome fantasies he’d had about his childhood friend. Heat-fueled near-hallucinations of Kacchan climbing into his nest and taking him, of them spending their heats and ruts together: a proposition Izuku was always far too cowardly to make.
He might be able to face down a bear, but when it comes to Kacchan? He would die before he dares to do anything that might jeopardize their friendship.

Izuku and Katsuki take cover from a sudden snowstorm in a small cave. Will their relationship survive or will this finally be their chance to sit and talk?
