Akari Kamijo is a twenty-five-year-old office worker who has begun to worry about her future as she watches her colleagues marry one by one and leave the company. Staring at her own hands, she laments that they are fat, a physical trait that has earned her the cruel nickname "tedeboo" from her frivolous department chief, who mocks her daily. Akari longs for happiness and wonders who will make her happy, but her self-consciousness about her appearance weighs heavily on her. Her otherwise gloomy office life takes an unexpected turn when she finds herself suddenly growing close to the company president's handsome son, setting the stage for an unlikely romantic development.
