In the end of season four, Oleg and Sophie get married, with the girls realizing they have their own business to worry about and their own dream to work towards, which leads to them quitting "The High" and coming back to their business.
The series chronicles the lives of two waitresses in their mid-20s (at the start of the series): Max Black (Kat Dennings), the child of a poor working-class mother and an unknown father, and Caroline Channing (Beth Behrs), who was born rich but is now disgraced and penniless because her father, Martin Channing, got caught operating a Bernard Madoff-esque Ponzi scheme.
The two work together at a Brooklyn diner, soon becoming roommates and friends while building toward their dream of one day opening a cupcake shop.
Set in the Williamsburg neighborhood of Brooklyn, New York City, the show's plot follows the lives of friends Max Black (Kat Dennings) and Caroline Channing (Beth Behrs).
Whereas Caroline was raised as the daughter of a billionaire, Max grew up in poverty, resulting in differing perspectives on life, although together they work in a local diner while attempting to raise funds to start a cupcake business.
Since its debut, the series has received a polarized response from critics and audiences alike.
