Hannah and Niall weren't the best of friends. In fact, they weren't ever really friends. Since Hannah was Louis's little sister (her brother being in a famous band), she had to be around him practically 24/7. Something stirred the pot between them, and they were having just a normal everyday fight they always have. But something goes awry. One accidental quick seal of the lips, and a nightmare had begun. They end up switching bodies. They both decided to keep it down low until they were back to normal,thinking it will happen overnight, but little did they know, that only love can cure the disease.
