[Verse 1]
툭 웃음이 터지면 그건 너
Tuk useumi teojimyeon geugeon neo
If I burst out into laughter, it's you
쿵 내려앉으면은 그건 너
Kung naeryeoanjeumyeoneun geugeon neo
If I slump down, it's you
축 머금고 있다면 그건 너
Chuk meogeumgo itdamyeon geugeon neo
If I'm holding something back, it's you
둥 울림이 생긴다면 그건 너.
Dung ullimi saenggindamyeon geugeon neo.
If there is a ringing, it's you.
[Pre-Chorus]
그대를 보며
Geudaereul bomyeo
As I look at you
나는 더운 숨을 쉬어요
Naneun deoun sumeul swieoyo
I let out a hot breath
아픈 기분이 드는 건
Apeun gibuni deuneun geon
Feeling like I'm hurt
그 때문이겠죠
Geu ttaemunigetjyo
Is because of you
[Chorus]
나를 알아주지 않으셔도 돼요
Nareul arajuji aneusyeodo dwaeyo
It's alright if you don't know
찾아오지 않으셔도
Chajaoji aneusyeodo
Or if you don't find me
다만 꺼지지 않는 작은 불빛이
Daman kkeojiji anneun jageun bulbichi
It's just that small light that won't go out
여기 반짝 살아있어요
Yeogi banjak saraisseoyo
Is twinkling and living right here
영영 살아있어요
Yeongyeong saraisseoyo
It lives forever
[Pre-Chorus]
눈을 떼지 못 해
Nuneul tteji mot hae
I can't take my eyes off of you
하루종일 눈이 시려요
Harujongil nuni shiryeoyo
So all day, my eyes hurt
슬픈 기분이 드는 건
Seulpeun gibuni deuneun geon
Feeling sad
그 때문이겠죠
Geu ttaemunigetjyo
Is because of you
[Chorus]
제게 대답하지 않으셔도 돼요
Jege daedaphaji aneusyeodo dwaeyo
It's alright if you don't answer me
달래주지 않으셔도
Dallaejuji aneusyeodo
Or if you don't comfort me
다만 꺼지지 않는 작은 불빛이
Daman kkeojiji anneun jageun bulbichi
It's just that small light that won't go out
여기 반짝 살아있어요
Yeogi banjak saraisseoyo
Is twinkling and living right here
세상 모든 게 죽고 새로 태어나
Sesang modeun ge jukgo saero taeeona
If everything in the world dies and reborn
다시 늙어갈 때에도
Dashi neulkeogal ttaeedo
If I grow old again
감히 이 마음만은 주름도 없이
Gamhi i maeummaneun jureumdo eopshi
This heart won't have any wrinkles
여기 반짝 살아있어요
Yeogi banjak saraisseoyo
It's twinkling and living right here
영영 살아있어요
Yeongyeong saraisseoyo
It lives forever
영영 살아있어요
Yeongyeong saraisseoyo
It lives forever
