Kim Jiyoung speaks as other women
In autumn 2015, Kim Jiyoung, a 33-year-old former marketing employee who left her job to raise her daughter, begins speaking in the voices of other women: her own mother, and a dead university friend who had once liked her husband. This starts shortly after she overhears office workers in a park call her a 'mom-roach', a slur for mothers seen as living off their husbands, while she drinks a cheap coffee with her baby. Her husband sends her to a psychiatrist, and the novel is his case notes on her life from birth to breakdown.
