Meet Gretchen and Jimmy. She's a cynical PR rep and he's a narcissistic British novelist. Impressed by each other's bad behavior at Jimmy's ex-girlfriend's wedding, they begin what they swear is a casual sexual relationship—until it turns out to be more than that.

Jimmy and Gretchen find themselves falling for each other despite their better judgment.

Gretchen makes Jimmy come over to her disaster of an apartment.

Jimmy begrudgingly joins Gretchen, Edgar, and Lindsay on a "Sunday Funday."

After Jimmy accidentally sleeps with an A-List celebrity, he and Gretchen embark on a sex arms race to even out their score.

Jimmy opens up emotionally, which completely freaks Gretchen out.
