A joint diary of five girls standing on the tulmutuous summit of adulthood.

The fashionable Hye-joo is focused on her career at a brokerage house. She's making a decent living, but her co-workers look down on her. Tae-hee is sick of living under the thumb of her domineering father. She spends her time doing volunteer work for a poet with cerebral palsy. Sullen Ji-young lives in poverty with her grandparents and struggles to find work. The girls, close friends in high school, find themselves drifting apart as their adult lives begin to take shape.
