SOMI SOHYE CHUNGHA YEONJUNG NAYOUNG SEJEONG DOYEON CHAEYEON YOOJUNG
Suddenly
SOMI
eojjeomyeon jaldoen iriya ppalgan noeulbitcheoreom
어쩌면 잘된 일이야 빨간 노을빛처럼
maybe it’s for the best, like the red glow of sunset
SOHYE
yeppeun neol bonaeya haetdeon geuttaega
예쁜 널 보내야 했던 그때가
the time I had to let pretty you go
CHUNGHA
meonameon huimihan gieok
머나먼 희미한 기억
a faraway, faint memory
YEONJUNG
ijen nae mamsok neol jiwoya hana
이젠 내 맘속 널 지워야 하나
should I now erase you from my heart
SOMI
jaryeogo nuwonneunde gapjagi neoe daehan saenggage jamgyeo
자려고 누웠는데 갑자기 너에 대한 생각에 잠겨
I lay down to sleep, but suddenly I’m lost in thoughts of you
NAYOUNG
In the midnight byeolcheoreom gamjeongdeuri ssodajyeo
In the midnight 별처럼 감정들이 쏟아져
In the midnight, emotions pour down like stars
SEJEONG
Ooh gapjagi neoe daehan geuriume samuchyeo
Ooh 갑자기 너에 대한 그리움에 사무쳐
Ooh, suddenly I’m pierced by longing for you
DOYEON
Till the morning geureoke achimi balgaone
Till the morning 그렇게 아침이 밝아오네
Till the morning, that’s how the dawn breaks
CHAEYEON
ijeuryeo nuwonneunde
잊으려 누웠는데
I lay down to forget
YOOJUNG
makhyeo inneun doro wi sumaneun cha jung hana
막혀 있는 도로 위 수많은 차 중 하나
one of the countless cars on the jammed road
SOHYE
nae maeum arajudeon neoneun eodi isseulkka
내 마음 알아주던 너는 어디 있을까
where are you, the one who understood my heart
DOYEON
meonameon huimihan gieok
머나먼 희미한 기억
a faraway, faint memory
CHUNGHA
ijen nae mamsok neol jiwoya hana
이젠 내 맘속 널 지워야 하나
should I now erase you from my heart
SEJEONG
jaryeogo nuwonneunde gapjagi neoe daehan saenggage jamgyeo
자려고 누웠는데 갑자기 너에 대한 생각에 잠겨
I lay down to sleep, but suddenly I’m lost in thoughts of you
NAYOUNG
In the midnight byeolcheoreom gamjeongdeuri ssodajyeo
In the midnight 별처럼 감정들이 쏟아져
In the midnight, emotions pour down like stars
YEONJUNG
Ooh gapjagi neoe daehan geuriume samuchyeo
Ooh 갑자기 너에 대한 그리움에 사무쳐
Ooh, suddenly I’m pierced by longing for you
DOYEON
Till the morning geureoke achimi balgaone
Till the morning 그렇게 아침이 밝아오네
Till the morning, that’s how the dawn breaks
CHAEYEON
ijeun jul aranneunde
잊은 줄 알았는데
I thought I’d forgotten
CHUNGHA
amuri aesseodo
아무리 애써도
no matter how hard I try
YOOJUNG
gwaenchaneun cheokhae bwado
괜찮은 척해 봐도
even if I pretend to be okay
SEJEONG
ijeul manhamyeon tto deuriwojineun gieok
잊을 만하면 또 드리워지는 기억
just when I could forget, the memory casts over me again
YEONJUNG
uri chueokdeul jakkuman areunareungeorijana
우리 추억들 자꾸만 아른아른거리잖아
our memories keep flickering before me
NAYOUNG
Lalala lalala lalalala lala
YOOJUNG
Lalala lalala lalalala lala
SOHYE
Lalala lalala lalalala lala
CHAEYEON
Lalala lalala lalalala lala
SOMI
neo mwonde gapjagi
너 뭔데 갑자기
who are you, all of a sudden
