My Neighbor, My Friend (Hayes Grier)

After Mackenzie comes back from visiting Paris with her dad, she sees her old best friend, Hayes Grier. After leaving for three years her and Hayes still kept in touch and texted but they have both changed a bit. Little did Hayes know Mackenzie had a crush on him and was planning on telling him the day before leaving but Hayes didn't go to the airport. Little did Mackenzie know Hayes didn't go because he felt the same way and just couldn't go. So when they see each other will they go back to normal or become more?
