4 lines from the song in Korean, with how they sound and what they mean. The full line-by-line breakdown lives in the app.
마치 세상이 문을 열 듯이Listen from this lineRomanization (as sung): ma·chi se·sang·i mu·neul yeol tteu·si
Meaning: As if the world were opening a door
Words in this line- 마치ma·chias if
- 세상이se·sang·iworld
- 문을mu·neuldoor
- 열yeolopen
- 듯이tteu·sias though
Word for word: Just-like world door open as-if.
Why it doesn't translate word for word: 열다 means to open, 문 means door, and 듯이 means as if. The ending -ㄹ 듯이 carries a comparison and hangs at the end of the phrase, which sounds odd word for word. The whole image conveys a feeling that a new world is opening up.
낯선 장면 속Listen from this lineRomanization (as sung): nat·sseon jang·myeon sok
Meaning: In an unfamiliar scene
Words in this line- 낯선nat·sseonunfamiliar
- 장면jang·myeonscene
- 속sokinside
Word for word: Unfamiliar scene inside
Why it doesn't translate word for word: 낯선 on its own means 'strange', 장면 means 'scene' or 'shot', and 속 means 'inside'. Together they mean 'in the middle of an unfamiliar scene', like stepping into a film frame. Korean puts the modifiers first, so the literal order sounds clumsy in English.
더 이상 꿈이 아닌 것 같아Listen to the first verse — freeRomanization (as sung): deo i·sang kku·mi a·nin geot kka·ta
Meaning: It no longer feels like a dream
Words in this line- 더deomore
- 이상i·sangbeyond this
- 꿈이kku·midream
- 아닌a·ninnot being
- 것geotthing
- 같아kka·taseems
Word for word: More beyond-this dream not-being thing seems.
Why it doesn't translate word for word: 더 이상 alone is 'more beyond this', but with the negative 아닌 it means 'no longer'. 것 같아 literally 'resembles a thing' is just the soft 'it seems'. So the literal text is odd, while the real meaning is 'this has become real'.
일렁여 꿈결처럼 (꿈결처럼)Listen to the first verse — freeRomanization (as sung): il·leong·yeo kkum·gyeol·cheo·reom (kkum·gyeol·cheo·reom)
Meaning: They ripple like a dream
Words in this line- 일렁여il·leong·yeoripples
- 꿈결처럼kkum·gyeol·cheo·reomlike a dream
- (꿈결처럼)(kkum·gyeol·cheo·reom)like a dream
Word for word: Ripples dream-flow-like (dream-flow-like).
Why it doesn't translate word for word: 일렁여 means 'to sway or waver', like water or flame. 꿈 is 'dream', 결 is 'flow, grain', 처럼 is 'like'; together 꿈결처럼 means 'as in a hazy half-dream'. Korean omits the subject, so English must add 'it all'.

How we make these breakdowns
theIDOL builds every breakdown with AI assistance and automated checks, and publishes a page only after it passes them. An AI model writes the meaning of each line and the word-by-word glosses from the song's timed lyrics. The pronunciation comes from our own rule-based Korean transcriber, which spells how the words sound when sung, sound changes included, not a letter-by-letter romanization. Pages that fail the audio-sync or translation checks are not published, and we quote only a few key lines. If you spot a mistake, write to support@theidol.ai and we will fix it.
