Kyokugen Fuufu

We weren't supposed to end up like this...

Marriage can change a person. But those changes can also mean new arguments, a loss of respect for your partner, and sometimes, the ultimate betrayal -- an extramarital affair. Introducing a collection of tales depicting marriages on the brink of crumbling and women seeking revenge on their cheating, good-for-nothing husbands.
