It was sent to US contemporary hit radio through Atlantic Records on July 24, 2018, as the fifth and final single from his second studio album, Voicenotes.

The song deals with Puth's reaction to his sudden fame, specifically his insecurities and anxieties.

[3][4] Described as an "introspective, autobiographical track", it heavily features "a plugging electric guitar riff" throughout, with "Puth's vocals syncing up to the instrumental during the verses".

[9] Salvatore Maicki of The Fader regarded the video as "a nice aesthetic throwback to the late 90s",[3] while PopSugar's Mekishana Pierre opined that Puth's character bears a resemblance to My So-Called Life's Jordan Catalano.

[11][12] On July 17, he performed the song during his television appearances on The Tonight Show Starring Jimmy Fallon, as well as the Citi Concert Series on Today three days later.
