Summary
Highlights
Rose, a football enthusiast, tries out for her high school team. During a demonstration, she accidentally hits a girl, April, who turns out to be quick-witted and joins Rose in a prank against some rude boys. They become best friends, sharing typical high school antics.
During sophomore year, Rose accidentally enters the boys' bathroom and encounters a handsome dark-haired boy with green eyes. They have a clumsy, humorous exchange, and she headbutts him. Later, in class, she discovers he's a new exchange student named Billy, and she's assigned to take him to the nurse, much to April's disappointment.
Rose and April notice Billy flirting with cheerleaders, but then they see a second, identical boy. It's Billy's twin brother, Blaine. Rose hatches a plan for her to date Billy and April to date Blaine, setting up a study date at the library.
During a snack run, Blaine 'slaps' Rose on the butt, claiming to remove a cockroach, leading to comical banter and a card swap. At the library, Rose and Billy have an awkward moment involving a large book and a sneeze. Later, Blaine reveals his prank and flirts with Rose, leading to an unexpected kiss. April witnesses it and feels betrayed.
Rose lies to April about the kiss, claiming she fainted and Blaine gave her CPR for a fake cancer diagnosis. April, believing the lie, plans a cabin trip to reconnect. There, Rose discovers Billy and Blaine are also present. Rose later stumbles upon an injured woman who turns out to be Billy and Blaine's mother, revealing their close family bond.
Rose realizes her feelings for Blaine but decides to step aside to preserve the twins' relationship. She tells Billy she needs to let both of them go. After her lie about cancer is exposed, Rose runs away to Europe, sending an apologetic email to April confessing her true feelings for Blaine.
Years later, Rose returns as a pediatrician. Billy and April, now married with twin daughters, visit her clinic. They reconcile, and April explains that Rose's actions led them to realize their own connection. Rose then finds hundreds of letters from Blaine at her dad's old house, revealing his enduring love.
Rose, in her excitement, rushes to Blaine's house, where she's met by a woman, believing it's Blaine's partner. Heartbroken, she drives to her high school football field where Blaine finds her. He explains the woman was his mother's assistant, and they confess their love, sharing a moment before a football interrupts them.
