A Hawaiian Christmas, an undercover investigation-and maybe a second chance at love. Mimi Sakai has held the infamous title of the Oldest Single Female Cousin in her family for many years now, but her independent streak enables her to ignore the nagging and pitying looks. When she spends Christmas in Hawaii to help her favorite aunty out at her high-end cosmetics store, Mimi is reunited with Tosh, a boy she wronged when she was much younger and much more stupid. She tries to meet with him to apologize, but she unexpectedly becomes embroiled in his undercover work. Security consultant Tosh Kusunoki has become a loner after being hounded by the gossip about his father's fatal car accident, which happened to also kill his girlfriend. He never expected to see Mimi again after all these years, nor could he have predicted that she would be caught up in his investigation into drugs on the North Shore. Mimi agrees to help Tosh, and as they work together, they fall back into the comfortable friendship they had in the past. But Mimi struggles with loneliness, with regret over who she used to be, and uncertainty over who she wants to become. She knows she's just a mass of emotional baggage and Tosh should run away screaming. Despite all that, could Mimi possibly hope to receive the gift of a Christmas romance in paradise?
