Background and Promotion

Melanie began recording the album in 2015 and finished in 2017.[4] It was originally set to be released in the fall of 2017, then got postponed to January 2018.

On April 13th, 2016, and May 17th, 2016, Melanie posted two photos on Instagram with lyrics in both captions, revealing two songs that would be on the second album. Those songs were later revealed to be High School Sweethearts and Lunchbox Friends.

On May 15th, 2019, a teaser trailer for the film was released, revealing that the official title of the film was "K-12". Melanie revealed the new website layout on the same day and a low-quality version of the album cover leaked through the site's source code. The next day, on May 16th, 2019, Melanie officially unveiled the album cover on all social media platforms, revealing that the album is also titled "K-12".

On May 22th, 2019, a second teaser trailer for the film was released. A third teaser was released on May 29th, 2019, along with the album and film's release date. On June 17th, 2019, a preview featuring clips of the movie and a snippet of a new song, later revealed to be Nurse's Office, was premiered at the MTV Movie Awards.

On January 10th, 2020, Melanie started a TikTok challenge for fans to show their best "handshake dance" to promote Lunchbox Friends as a single.[6]


The album is set in Cry Baby's school and is told from her perspective. According to Melanie, it is Cry Baby stepping outside of her family and love life and acting as a narrator for the album.[7]

The album also introduces new characters, specifically friends of Cry Baby, at her school, although Cry Baby is still a main focus.[8] According to Melanie, "You're not learning about her, you're learning about the place that she's in and her perspective".[9]
