The Babysitter and the Brat [A NaLu Fanfiction]

Lucy Heartfilia is a high school student, and babysits Makarov's adopted grandchildren to earn money. She ran away from her drunk father, Jude Heartfilia. As Lucy struggles to fare for herself, she discovers joy in babysitting, especially with some interesting kids. One kid catches Lucy's eye; the boy with the salmon hair. "It's SALMON, not pink!" he constantly screams. He seems to be a bit of a brat, always demanding something, but when Lucy finds him crying in his bedroom, she wants to know what's going on.
One day, Lucy is taking a walk through the woods, and a natural phenomenon happens. She falls asleep for 7 years in a moss grown cave, known to be the home of a powerful deity. When she wakes up, she finds that the world has moved on without her. She quickly finds her old apartment (she rents it again), and keeps studying at high school, but she's also desperate to get a job.
On her first day of high school in 7 years, she meets a certain salmon-haired boy. Will this fateful encounter mark the start of something new?
