Everything Has Changed (A Darren Espanto Story)

Cassidy Villegas and Darren Espanto were best friends ever since they were two years old. They literally did EVERYTHING together. They were inseparable.
All of a sudden, Darren moves away from her to the Philippines. He never called, he never texted, he never e-mailed. They lost all contact.
3 years later, her so called best friend comes back. He realizes there's something different about her now. She shuts everybody out and there's no way of getting to her. She's no longer that friendly girl that she was three years ago. In other words, EVERYTHING HAS CHANGED
