Underwater (Ziall)

When Zayn goes on a holiday in Spain with his family he meets a beautiful girl who takes him to a city underwater. That is where he meets Niall. Niall is the guy at school that everyone respects and greet in the hall. Zayn is the guy at school that no one really likes and label him as an uncool loner. But when Niall sees Zayn he immediately feels some sort of attraction. Tension is in the air, but why? Those butterflies that are in their stomachs are making it hard to think clearly around each other. How would the butterflies feel if they had humans running inside of their stomach? It would be quite disturbing.
