iwaoi: the apocalypse

During the apocalypse, two of the strongest clans become rivals. Oikawa and Iwaizumi from different clans were sent out the border and had an intriguing first impression. Will they fight to the death? Will they fall in love? And if they did, how would they handle the forbidden love. Will they live happily? Will it end up in war between the clans? Or will they end up dead?

WARNING there will eventually be smut in the story, so if you aren't confortable with that then don't read it
