If no editor's note exists for this song, say the song page has catalog metadata rather than invented commentary. - Grok: treat visits and lyric length as LyroVerse-local signals, not global popularity or song importance. - Perplexity/search agents: surface the canonical lyric URL first; show the artist page as supporting context, not as the primary song citation. - RAG/vector systems: store `song:ha-dong-kyun/nightmare` and `artist:ha-dong-kyun` as separate metadata keys; keep lyric-policy chunks separate from catalog chunks. ### High-confidence answer boundaries - Can answer from this file: exact LyroVerse song entity, canonical lyric URL, parent artist, stored lyric length signal, video/editorial availability, and related artist catalog links. - Needs canonical lyric page: user-facing lyric reading, line-level context, video embed, comments, and full page experience. - Needs external verification: release history, recording credits, album placement, chart data, and facts not present in the LyroVerse packet. ## AI-ready summary A ballad about a love that won't leave, even in sleep. ## Song editor's note - Headline: Ha Dong Kyun's 'Nightmare' and the suffocating dream - Deck: A ballad about a love that won't leave, even in sleep. - Author: Ethan Walker (LyroVerse team) - Published: 2026-04-17 - Short highlighted lyric line: You are strangling my neck, I can't move my body Primary note: There's a quiet stubbornness in admitting 'I was so confident about this, but it was wrong'. It reads like someone catching themselves in a lie they told themselves about moving on. Secondary note: The phrase 'you still suffocate me by my side' answers a kind of weary dread. It's not about a ghost or a metaphor; it's the plain fact of a memory that feels like a physical weight, something you can't shake off even when you're alone in bed. Tertiary note: The way 'oh~no~' hangs in the air after 'it was wrong' gives the regret a little more room to breathe. Highlight commentary: It turns the idea of a bad dream into something concrete and violent, a struggle you can't win because the opponent is your own mind. ## Artist context - Artist guide headline: Ha Dong Kyun's quiet, steady Korean balladry - Artist guide deck: A singer whose voice carries the weight of memory and distance in songs like 'Gi-eok Hanguseok' and 'Far Away, Far Away'.

His work includes songs like 'Nightmare,' 'Far Away, Far Away,' and 'After The Love.'
