• "One Star" is about discovering that a lover has been unfaithful. Deryk, a musician from Auckland, New Zealand, wrote it from personal experience. She penned the song while still mired in her own hard feelings. She told Prelude Press, "Loss and betrayal can stop time, I swear. The moment you find out, it's like your whole body deflates and while you're trying to come to terms with it, the rest of your world carries on, judging you for not recovering in two minutes."
• This was the second song released by deryk, following "Call You Out." She was 24 years old at the time.
• The video for the song features scenes of deryk interspersed with footage of an emaciated man lifting weights. Deryk found the footage of the man on Film Supply. On her YouTube post for the song, she wrote, "I like how weak he looks but how triumphant he seems."
