The song is widely available on unofficial platforms such as SoundCloud's "Unreleased Collection" and various fan-curated YouTube playlists.

"I've been broken for so long / But when I find you could you mend me?"

Lyrically, "Eveline" is a mid-tempo, melodic pop ballad that captures a sense of longing and a desperate search for healing. The song's namesake, "Eveline," appears to be a personification or a specific figure Demi addresses while navigating feelings of isolation and a "broken" state. Key lyrics from the track include:

"Eveline, you're taking up this lonely heart of mine / 'Cause all these faces that I meet just don't feel the same."
