Two years ago, Nina married a man she had never met. She didn’t know his name or his age; she knew nothing about this person she was married to. Their marriage was nothing more than a contract with conditions, and one of the clauses was that she should not sleep with another man.

Yet, Nina lost her virginity to a stranger when she knocked at the wrong door one night.

With the compensation she had to pay weighing her down, she decided to draw up a divorce agreement on her own.

When she finally met her husband to hand over the papers, she was shocked to find that her husband was none other than the man she had “cheated” on him with!
