On January 8, Tom Hansen meets Summer Finn, his boss's new assistant. Tom is trained as an architect but works as a writer at a greeting card company in Los Angeles. After discovering they have a similar taste in music, they have a conversation about love at a karaoke night; Tom believes in it, but Summer does not. Tom's friend and co-worker McKenzie drunkenly reveals that Tom likes Summer, which Tom asserts is only "as friends", something Summer agrees with. A few days later, Summer kisses Tom in the copy room at work. During the next few months, Summer and Tom grow closer.
Tom shows Summer his favorite spot in the city, which overlooks a number of buildings he likes, though the view is somewhat spoiled by parking lots. After several months of dating, both Tom's friends and his preteen half-sister Rachel push him to question Summer where they are in their relationship, though Summer brushes this off, saying that it should not matter if they are both happy. One night, Tom gets into a fight with a man who tries to pick up Summer in a bar, which causes their first argument. They makeup and Summer concedes Tom deserves some certainty, but that his demand that she promises to always feel the same way about him would be impossible for anyone to make.
On day 290, they are hanging out in a cafe. Tom wants to go back to Summer's place but she insists on seeing The Graduate and weeps at the ending, which surprises Tom as he'd always thought it was a romantic fairy tale. They visit the record store, but Summer is distracted, appears to have lost interest in Tom, and kisses him goodnight. Tom tempts her with an offer of pancakes at a diner, where Summer casually announces that the relationship hasn't been working and breaks up with Tom while they are waiting for the food to arrive. Summer wants them to remain friends, but Tom is devastated. ReadMore>
