ILLIT’s “jellyous” is about a girl who gets jealous and flustered over a crush whose kindness she can't read. The title blends jelly with jealous, matching the sweet heart shapes and candy-like flavors of her daydreams, which cloud over with a sour red taste when she wonders if he treats everyone this way. She pushes her worries off to another day and tries to keep her heart light.

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.
너로 가득 찬 맘 super jellyousListen from this lineRomanization (as sung): neo·ro ga·deuk chan mam super jellyous
Meaning: My heart, filled with you, is super jealous
Words in this line- 너로neo·rowith you
- 가득ga·deukfull
- 찬chanfilled
- 맘mamheart
Word for word: With-you fully filled heart super jellyous
Why it doesn't translate word for word: 너로 means 'with/by you', 가득 'fully', 찬 'filled': together they say 'my heart holds only you'. 맘 is the casual word for heart or mind. 'Jellyous' again plays on 'jealous', so the odd jelly image is really just jealousy.
밤새 달린 DM 끝에 너의 잠 확 깨는 메시지Listen from this lineRomanization (as sung): bam·sae dal·lin DM kkeu·te neo·ui jam hwak kkae·neun me·si·ji
Meaning: After a night of DMs, a message that snaps you awake
Words in this line- 밤새bam·saeall night

- 끝에kkeu·teat the end
- 너의neo·uiyour
- 잠jamsleep
- 확hwaksuddenly
- 깨는kkae·neunwaking
- 메시지me·si·jimessage
Word for word: All-night run DM at end your sleep suddenly waking message
Why it doesn't translate word for word: 달린 means 'running', but for chat it means 'ran on nonstop'. 끝에 is 'at the end', i.e. after the long chat. 확 깨는 is 'suddenly waking', and 잠 깨다 literally 'breaks sleep', so the message wakes you up instantly.
혹시나 이게 다 착각이면 어떡해?Listen to the first verse — freeRomanization (as sung): hok·ssi·na i·ge da chak·kka·gi·myeo neo·tteo·kae?
Meaning: What if all this is just my misunderstanding?
Words in this line- 혹시나hok·ssi·nawhat if
- 이게i·gethis
- 다daall
- 착각이면chak·kka·gi·myeoif misunderstanding
- 어떡해?neo·tteo·kae?what do I do
Word for word: By chance this all, if misperception, how do I do?
Why it doesn't translate word for word: 혹시나 alone is 'by any chance', 착각 'misperception', 이면 'if it is'. 어떡해 is a contraction of 어떻게 해, 'what do I do?'. Together they form an anxious 'what if I imagined it all?'.
Hey hey hey 그런 건 불법인걸Listen to the first verse — freeRomanization (as sung): Hey hey hey geu·reon geon bul·beo·bin·geol
Meaning: Hey, hey, hey, that kind of thing is illegal, you know.
Words in this line- 그런geu·reonthat kind of
- 건geonthing (topic)
- 불법인걸bul·beo·bin·geolis illegal, you know
Word for word: Hey hey hey that-kind-topic illegal-you-know.
Why it doesn't translate word for word: 그런 건 is 'that kind of thing' and 불법 is 'illegal', a legal word on its own. Together they make a joke that being this charming should be against the law. The -ㄴ걸 ending adds a 'you know' tone.
