Emerald Green with Turquoise Mixed in and Little Flecks of Brown

This is a fanfiction that I'm writing about James Sirius Potter and a new character, Ashley Cummings. James is the social, cool Gryffindor at Hogwarts and Ashley is a shy, Hufflepuff bookworm. When their paths cross one day in the hallway via head-butt, was it all accidental, or did fate have specific plans for them?
