A movie based on a controversial best-selling novel that chronicled the everyday sexism faced by women topped South Korea's box office this week, reigniting a national debate over women's roles in a historically male-dominated society.

"Kim Ji-young, Born 1982" opened in last week and immediately highlighted divisions over sexism, the anti-harassment #MeToo movement and feminism.

The story follows a married woman in her 30s who feels forced by social circumstances and opinions to give up her work and dreams in order to raise her young child.
