2WayMirror

The cover of the EP depicts Gabbie looking through a see-through shower door, on which a message has been left on the steam. Hanna had her followers choose between this and another potential cover, which displayed a faux iMessage chat, on Instagram.

This cover references the lyrics to the song Perfect Day (A True Story).[7]

Hanna initially began the project as a single titled "Butterflies", before the project eventually became an EP.[8] The first song she wrote and recorded for the EP was "Broken Girls" in December 2018.[3][9]

After the EP was announced, Hanna had fans vote on two album covers, and whichever one won would be the official cover of the EP.[10]

Hanna initially teased five songs to be on the EP. "Medicate" was confirmed as the lead single and the four other tracks were confirmed: "Butterflies", "Perfect Day (A True Story)", "Pillowcase", and "Broken Girls". However, a sixth song, "Goodbye, for Now", was leaked by Hanna's producer, Alina Smith.[11] Hanna later confirmed the EP will contain 13 tracks total,[12] but reaffirmed its status as an extended play, and would not be considered an album.[13] Hanna announced on May 12, 2019 that she completed the EP.[14]

Hanna has described 2WayMirror as a "perfect loop" due to the fact that "I'm Sorry" loops directly into "She Wrote It About You?", completing the loop. Other tracks such as "She Wrote It About You?" and "Broken Girls" blend together musically.[15] Even though 2WayMirror contains 13 tracks, Hanna has reaffirmed the work's status an EP, despite streaming services labeling it as an album.[16] The songs on the EP detail a tumultuous relationship with one of Hanna's ex boyfriends, revealed in a YouTube video in which the two appeared,[3] with the exception of the second single, "Butterflies", which is confirmed to be about two men Hanna was interested in at the same time.[17] Other themes explored on the EP include depression and heartbreak.[18]

The remaining 7 tracks are either intros, outros or bits of voice messages that she had exchanged with her then-boyfriend during their breakup, and serve to contextualise the song and frame the EP within the narrative of her breakup.

"Medicate" was released on February 1, 2019 as the lead single from 2WayMirror.[19] It was accompanied by a music video.[20] Commercially, it reached number 31 on the US Digital Songs chart, while becoming her first single to chart in New Zealand.[21][22] "Butterflies" was released alongside the EP as the second single on May 31, 2019.[23][24] It was also accompanied by a music video.[25] Commercially, it reached number 37 on the New Zealand Hot Singles chart.[26] While it was not released as a single, "Perfect Day (A True Story)" was also accompanied by a music video.[27] Hanna later said she is filming a music video for every song on the EP.[28] Hanna confirmed on July 21, 2019 that filming for the "Pillowcase" music video had begun.[29] The music video for "Pillowcase" was released on August 17, 2019, which also included the interlude songs "This Isn't Fun For Me" and "Exhausted". The music video for "Broken Girls" and "Broken Boys" was confirmed in a YouTube video uploaded by Hanna.[30] The "Broken Girls" music video was released on November 16, 2019. The music video for "Goodbye, For Now" was released on September 3, 2020.[31]

Hanna performed acoustic versions of "Pillowcase" and "Butterflies" with Elli Moore at VidCon LA on July 13, 2019. Each song from the EP was performed as well as the song "Antisocial Media" later the same day.[33]
