Aubrey has changed. She's a completely different person than who she used to be. She's a lot colder, and a lot more wary now. Nate has changed as well. He's not the same person that he used to be, and he allows himself to feel things, deeply. He's trying to do whatever it takes to win Aubrey back. A lot happens in this chapter of Nate and Aubrey's story. Love, hate, regret, denial, are all constant themes.
