Honor Sheldon is a plain but diligent twenty-five-year-old who has been living in the shadow of her supermodel sister, Helen. But then, while helping out at the Valentine’s Day Ball, a charity event, the goddess of love finally smiles upon her. Suffering from a severe cold that night, she takes medicine and accidentally falls asleep on a bench outside. When she wakes up, she finds herself in her car with a rose next to her. A few days later, she receives a letter from the mysterious man who rescued her that night. The letter is addressed to H. Sheldon, so she writes him back and they start exchanging letters. They talk about books, international affairs and life in general, but soon his letters become more passionate. Her heart beats faster and she starts falling for her phantom lover. But this happiness comes to an abrupt end with a shocking discovery—when she receives the next letter, she finds out that he thought he was actually writing to Helen the whole time…not Honor.
