Hangul Lyrics
쿵 두근
숨길 수 없어 난
쿵 두근
두근
Knock, knock, knock
La-la-la-la-la-love (Wow)
La-la-la-la-la-love (Yeah)
La-la-la-la-la-love
어라 이거 혹시?
새파란 하늘빛이 눈부신 날
맘엔 천둥번개가 예고도 없이 (이미 K.O.)
잠깐 또 스쳐 간 너의 시선에
Bi-bi-bi 울려대는 심장은 비상 사태
Oh, why? 이상해
몰랐던 감정들로 조금씩
물들어가는 days 이름조차 모르지만
내 인생의 히로인 널 찾아낸 거야
그래 난 오직 너를 위한 (KO1야)
네 맘을 열기 위한 (Key야)
내게 기대면 돼 (KO1KEYZ)
오래 기다렸어 my love
더 가까이 와줄래 (KO1KEYZ)
널 만나기 위해
난 태어난 거야
네 맘의 문을 열어줄래?
쿵 두근
숨길 수 없어 난
쿵 두근
두근-두근-두근 (사랑이야?)
(What's your name?) 이름이 뭐야?
이 말툰 좀 아닌데
(What's your name?) 몇 번째인 거야
입꼬리가 떨려오네
안녕 그 인사에
심장이 막 터질듯 해
어젯밤 꿈에서
완벽했었는데
두 손을 모아 기도해
부디 이런 내게 용기를 주세요
그래 난 오직 너를 위한 (KO1야)
네 맘을 열기 위한 (Key야)
내게 기대면 돼 (KO1KEYZ)
오래 기다렸어 my love
더 가까이 와줄래 (KO1KEYZ!)
널 만나기 위해
난 태어난 거야
네 맘의 문을 열어줄래?
처음이야 이런 내 주체할 수 없는 맘
어디에 있든지 자꾸 너를 찾게 되는 걸
사랑에 빠지면 always, 시작해 빛나는 world
네 마음의 문을 여는 key 내가 될 테니까
가슴이 두근두근 큥큥 (Hoo)
하늘 위로 슝슝 (Yeah)
콧노래가 룰루
사랑인 것 같아
나에게 보여준 네 맘은 (KO1야)
내 세상을 바꾼 (Key야)
안녕 내 이름은 (KO1KEYZ)
앞으로도 잘 부탁할게
손을 잡아줄래 (KO1KEYZ)
놓치지 않을게 (Ooh)
네가 가르쳐준
기분 좋은 사랑의 떨림
쿵 두근
넌 이미 알잖아 (Yeah)
쿵 두근
두근-두근-두근

English Translation
Thump, thump
I can’t hide it
Thump, thump
Thump
Knock, knock, knock
La-la-la-la-la-love (Wow)
La-la-la-la-la-love (Yeah)
La-la-la-la-la-love
Wait, could this be…?
On a day when the bright blue sky is dazzling
Thunder and lightning strike my heart without warning (Already K.O.)
Just from your gaze that briefly passed by again
My heart rings bi-bi-bi — it’s an emergency
Oh, why? It’s strange
With emotions I never knew before, little by little
Days start to color
I don’t even know your name
But I’ve found you, the heroine of my life
Yes, I exist only for you (KO1)
To open your heart (Key)
You can lean on me (KO1KEYZ)
I’ve waited so long, my love
Will you come a little closer? (KO1KEYZ)
I was born
To meet you
Will you open the door to your heart?
Thump, thump
I can’t hide it
Thump, thump
Thump-thump-thump (Is this love?)
(What's your name?) What’s your name?
This way of speaking feels a bit off
(What's your name?) How many times is this?
The corners of my mouth are trembling
With that “hello” greeting
My heart feels like it’s about to burst
In last night’s dream
I was perfect
I clasp my hands and pray
Please, give courage to someone like me
Yes, I exist only for you (KO1)
To open your heart (Key)
You can lean on me (KO1KEYZ)
I’ve waited so long, my love
Will you come a little closer? (KO1KEYZ!)
I was born
To meet you
Will you open the door to your heart?
This is the first time — this feeling I can’t control
Wherever I am, I keep looking for you
When you fall in love, always, a shining world begins
I’ll become the key that opens the door to your heart
My heart goes thump-thump, kyung-kyung (Hoo)
Up into the sky, whoosh-whoosh (Yeah)
Humming a tune, lululu
I think this is love
The heart you showed me (KO1)
Changed my world (Key)
Hello, my name is (KO1KEYZ)
Please take care of me from now on
Will you hold my hand? (KO1KEYZ)
I won’t let go (Ooh)
The pleasant flutter of love
That you taught me
Thump, thump
You already know, right? (Yeah)
Thump, thump
Thump-thump-thump
Indonesian Translation
Berdebar, berdebar
Aku tidak bisa menyembunyikannya
Berdebar, berdebar
Berdebar
Tok, tok, tok
La-la-la-la-la-cinta (Wow)
La-la-la-la-la-cinta (Yeah)
La-la-la-la-la-cinta
Eh, mungkinkah ini…?
Di hari ketika cahaya langit biru cerah begitu menyilaukan
Petir dan guntur menghantam hatiku tanpa peringatan (Sudah K.O.)
Hanya dari tatapanmu yang sempat lewat lagi
Jantungku berbunyi bi-bi-bi — ini keadaan darurat
Oh, kenapa? Aneh sekali
Dengan perasaan yang sebelumnya tak kukenal, sedikit demi sedikit
Hari-hari mulai berwarna
Namamu pun belum kuketahui
Tapi aku telah menemukanmu, tokoh utama dalam hidupku
Ya, aku hanya untukmu (KO1)
Untuk membuka hatimu (Key)
Kamu bisa bersandar padaku (KO1KEYZ)
Aku sudah lama menunggumu, cintaku
Maukah kau datang sedikit lebih dekat? (KO1KEYZ)
Aku lahir
Untuk bertemu denganmu
Maukah kau membuka pintu hatimu?
Berdebar, berdebar
Aku tidak bisa menyembunyikannya
Berdebar, berdebar
Berdebar-berdebar-berdebar (Apakah ini cinta?)
(What's your name?) Siapa namamu?
Cara bicaraku ini agak aneh
(What's your name?) Sudah berapa kali ini?
Sudut bibirku mulai bergetar
Dengan sapaan “halo” itu
Jantungku rasanya mau meledak
Di mimpi semalam
Aku sempurna
Aku merapatkan kedua tangan dan berdoa
Tolong, berikan keberanian pada diriku yang seperti ini
Ya, aku hanya untukmu (KO1)
Untuk membuka hatimu (Key)
Kamu bisa bersandar padaku (KO1KEYZ)
Aku sudah lama menunggumu, cintaku
Maukah kau datang sedikit lebih dekat? (KO1KEYZ!)
Aku lahir
Untuk bertemu denganmu
Maukah kau membuka pintu hatimu?
Ini pertama kalinya — perasaan yang tak bisa kukendalikan
Di mana pun aku berada, aku terus mencarimu
Ketika jatuh cinta, selalu, dunia yang bersinar dimulai
Aku akan menjadi kunci yang membuka pintu hatimu
Hatiku berdebar-debar, kyung-kyung (Hoo)
Melayang ke langit, syung-syung (Yeah)
Bernyanyi kecil, lululu
Sepertinya ini cinta
Hati yang kau tunjukkan padaku (KO1)
Mengubah duniaku (Key)
Halo, namaku (KO1KEYZ)
Mulai sekarang, tolong jaga aku ya
Maukah kau memegang tanganku? (KO1KEYZ)
Aku tidak akan melepaskannya (Ooh)
Getaran cinta yang menyenangkan
Yang kau ajarkan padaku
Berdebar, berdebar
Kau sudah tahu kan? (Yeah)
Berdebar, berdebar
Berdebar-berdebar-berdebar
