Summary
When Prime Omega Izuku Midoriya's bond is severed by his alpha's death, his body begins shutting down. Average alphas can't help him, their knots are too small, their scent too weak, the biological mismatch too severe. He needs a Prime Alpha, and there's only one compatible enough to save his life: Katsuki Bakugou, the man he's spent years avoiding because their attraction is too dangerous, too consuming, too inevitable.
The bridge bond protocol is supposed to be temporary, regular knotting and intimate contact to stabilize Izuku's failing body until he heals. But Prime biology doesn't care about intentions. Their scent glands swell at proximity. Their bodies prepare for permanent bonding. And neither can tell where medical necessity ends and something deeper begins.
Caught between death and a bond neither consented to, they must navigate the brutal physical reality of Prime compatibility, and decide if what's between them is only biology, or something worth choosing.
