The beginning of US.

A story about a guy who fell really hard for a girl that he hardly knew. They were both, kind of, strangers to each other at first, they knew nothing about each other. They only knew the name of the other, age and the fact that they go to the same school with each other. Even though they go to the same school, they don't see or talk to each other much since they are in different year group. It all started in the spring holiday. Their families with a few others went to Turkey together to explore it. And that was the beginning of their 'love' story...
