Worlds End Harem x Male reader

Have you ever thought what will happen, When all the male will disappear or die all of a sudden?.

Seems like a ridiculous thought right? Well no, A world that has fallen in an apocalypse where the male population is dying.

If you were one of the male that survived? what will you do? help humanity? or let it die? or become powerful to destroy the people that destroyed you?.
