Following her parents' divorce, Darby Carter struggled to make connections as an adolescent and, later, as a NYU student, until she meets Augie Jeong at a karaoke party. After their whirlwind night together and several days spent waiting by the phone for Augie's follow-up "WYD" text, Darby quickly finds herself in a comfortable, full-blown relationship.

After hours spent stalking her ex's new girl on social media, she winds up connecting with an overeager, romantically bruised.
