This is not a typical k-drama, its more in the style of Charlie Brooker's Black Mirror, and I think it will appeal to anyone to likes a drama that makes you think hard, even if its unpleasent.

Its starts as what you think as a fairly standard modern plot, and leads you to think how ordinary people end up doing things, just because they were in the wrong place at the wrong time, or had the wrong sort of parent.
Its ugley no holds barred acting, and Yeom Hye-ran should win awards for this, just watching is exhausting.
As a couple we binge watched over three nights, having seen the all of the Glory , I think its even more powerful because it is an every day tale, there is no filter, being bad is not made glossy, no smart houses, the actors often without make up.
There is some sort redemption at the end, which is perhaps the only light touch, but no man saves these women, they have to save themselves.
