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-hyun-sang/us` and `artist:ha-hyun-sang` 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 Korean ballad about the stubborn pull of a past relationship, even after you've decided to leave. ## Song editor's note - Headline: Ha Hyun Sang's 'Us' and the memory of us - Deck: A Korean ballad about the stubborn pull of a past relationship, even after you've decided to leave. - Author: Ethan Walker (LyroVerse team) - Published: 2026-04-17 - Short highlighted lyric line: But can't stop thinking about the time when we were... Primary note: Most breakup songs fixate on the other person or the pain. This one fixates on the pronoun. 'Us' is the ghost he's haunted by, a finished thing he keeps turning over in his hands. The insistence makes the refusal to go back feel less like strength and more like a spell he's trying to believe. Secondary note: The phrase 'the time when we were us' does a lot of heavy lifting. It's not just remembering a person, but a specific state of being, a 'we' that's now gone. The Korean verses detail what was lost or thrown away: a dream, a path, a summer, an autumn. 'Us' becomes this sealed-off season he can't stop revisiting, even though he knows he can't return. Tertiary note: The way the English chorus bluntly states the conflict, then the Korean verses unfurl the specific, sensory memories that fuel it. Highlight commentary: It's that word 'us', past tense, defined, almost a proper noun. It pins the longing not to a person, but to a finished chapter they both inhabited. ## Artist context - Artist guide headline: Ha Hyun Sang's quiet, healing songs - Artist guide deck: A Korean singer-songwriter whose gentle piano ballads offer comfort and reflection.
