Dawson is just 17, and just days away from aging out of the system. She can't wait for that day to come, because then she can stay at the orphanage and help the boys she loves run it.
Jack, Jonah, Corbyn, Daniel, and Zach are all at least 18, and they work together to run Weeping Willow's orphanage. Like Dawson, Zach was an orphan too. He aged out and offered to stay and help.
Before Dawson's 18th birthday however, she has to do the hardest thing. She has to figure out how to say goodbye.
