아무 일도 없는 듯이
눈을 감아 초를 불지
매일 너와 함께 있고 싶은
맘을 녹인
너는 모를 나의 비밀
Party가 막을 내려
난 조금 더 있고 싶어
가는 시간이 아쉬운걸
It’s your birthday
너와 터트리던 Champagne
온통 달콤하던 This cake
처음처럼 난 Celebrate
Back in the day
눈치채지도 못하게
초가 타기 전 네 옆에
다시 돌아가 Celebrate
반대로 된 시침같이
나 혼자만 또 시간을 되감지
빠져드는 Sweetness
다시 봐도 난 설레지
황홀한 Feeling
잊지 못할 Everything
모두가 멈추면 난
다시 너의 곁으로 가
환히 웃으며 눈을 맞춰
It’s your birthday
너와 터트리던 Champagne
온통 달콤하던 This cake
처음처럼 난 Celebrate
Back in the day
눈치채지도 못하게
초가 타기 전 네 옆에
다시 돌아가 Celebrate
영원하고 싶은 맘 꿈같은 이런 밤
재촉하듯 시곈 끝을 향해 가
Back in the day
아쉬워지는 마음에
멈춰 세워 난 Turning back
다시 시작해 Celebrate
일렁인 두 눈에 서로를 담아봐
We’ll celebrate through the night
똑같은 장면도 새로워 You and I
We’ll celebrate and cross the time
It’s your birthday
너로 가득한 Everyday
돌고 돌아 난 네 곁에
다시 함께 해 Celebrate
Back in the day
모든 순간이 소중해
나만 아는 이 기억에
진심을 다해 Celebrate
영원하고 싶은 맘 꿈같은 이런 밤
재촉하듯 시곈 끝을 향해 가
Back in the day
아쉬워지는 마음에
멈춰 세워 난 Turning back
다시 시작해 Celebrate

as if nothing happened
Close your eyes and blow out the candles
I want to be with you every day
melted my heart
my secret you don't know
Party comes to an end
i want to stay a little longer
I miss the time to go
It's your birthday
Champagne that exploded with you
This cake was sweet all over
Like the first time, I Celebrate
Back in the day
without even noticing
Before the candle burns, beside you
Celebrate again
like the hour hand reversed
I rewind the time alone
Falling Sweetness
I get excited when I see you again
ecstatic feeling
Unforgettable Everything
When everyone stops
go back to you
Smile brightly and make eye contact
It's your birthday
Champagne that exploded with you
This cake was sweet all over
Like the first time, I Celebrate
Back in the day
without even noticing
Before the candle burns, beside you
Celebrate again
I want to be forever, this dream-like night
Go towards the end of the clock as if urging
Back in the day
in the heart of regret
I stop and turn back
Start again Celebrate
Put each other in your swaying eyes
We'll celebrate through the night
Even the same scene is new You and I
We’ll celebrate and cross the time
It's your birthday
Everyday full of you
I turn round and round by your side
Let's be together again Celebrate
Back in the day
every moment is precious
In this memory that only I know
Celebrate with all your heart
I want to be forever, this dream-like night
Go towards the end of the clock as if urging
Back in the day
in the heart of regret
I stop and turn back
Start again Celebrate
