While the official version is a clear journey to self-acceptance ("I'm the one I should love"), the demo leans toward themes of longing and needing someone by one's side ("Please be by my side, you / You're my lullaby").
The demo's lyrics are almost entirely in English and are considered "guide lyrics"—often containing grammatical errors or "gibberish" intended to establish vocal progression and melody rather than a finished message.
Unlike the polished final version, the demo is characterized by its and raw vocal delivery .
