The ending in the movie differs from the ending in the novel. In the movie, there is a more hopeful ending for Sutter, and his relationship with Aimee is left slightly open ended. In the book, Sutter lies to Aimee, telling her that he cannot go to Philadelphia right after graduation like they had planned because he must attend summer school. He convinces her to go without him and promises her that he will go once he finishes school. However, Sutter tells the reader that he will never contact her again and will block her email and phone number. The book ends with Sutter drunkenly walking down the street by himself with a bleeding finger that he cut while opening a beer bottle.
