[트와이스 "KNOCK KNOCK" 가사]

[Verse 1: Nayeon, Chaeyoung, Dahyun & Sana]
열두시가 되면 닫혀요
조금만 서둘러 줄래요
Knock, knock, knock, knock, knock on my door
Knock, knock, knock, knock, knock on my door
밤이 되면 내 맘속에
출입문이 열리죠
누군가 필요해 (Someone else!)

[Verse 2: Jihyo, Jeongyeon, Momo, Mina & (Sana)]
자꾸자꾸 서성이네
몰래 몰래 훔쳐보네
Knock, knock, knock, knock, knock on my door
Knock, knock, knock, knock, knock on my door
보나마나 또 playboy
떠보나마나 bad boy
확신이 필요해 (Knock knock!)

[Chorus: Nayeon, Mina + Tzuyu, All, Jihyo & (Momo + Sana)]
내 맘이 열리게 두드려줘
세게 쿵 쿵 다시 한번 쿵 쿵
Baby, knock, knock, knock, kno-knock on my door
Knock, knock, knock, kno-knock
쉽게 열리지는 않을 거야 (Say that you’re mine!)
내일도 모레도 다시 와줘
준비하고 기다릴게 (Knock, knock, knock)
(Baby, knock, knock, knock, kno-knock on my door
Knock, knock, knock, kno-knock)
들어도 계속 듣고 싶은 걸
Knock on my door

[Verse 3: Chaeyoung, Dahyun & Jeongyeon]
필요 없어 gold key or get lucky
진심이면 everything’s gonna be okay
어떡해 벌써 왔나 봐
잠시만 기다려 줄래요
혼자 있을 때 훅 들어와
정신 없이 날 흔들어 놔
지금이 딱 널 위한 show time, make it yours

[Verse 4: Tzuyu, Mina, Jeongyeon & Chaeyoung]
댕 댕 울리면 매일 찾아와줄래
뱅뱅 돌다간 잠들어 버릴 걸요
Knock, knock, knock, knock, knock on my door
Knock, knock, knock, knock, knock on my door
Come in, come in, come in baby, take my hands

[Chorus: Sana, Mina + Tzuyu, Nayeon, All, (Jihyo) & [Momo + Sana]]
내 맘이 열리게 두드려줘
세게 쿵 쿵 다시 한번 쿵 쿵
Baby, knock, knock, knock, kno-knock on my door
Knock, knock, knock, kno-knock
쉽게 열리지는 않을 거야 (Say that you’re mine!)
(내일도 모레도 다시 와줘
준비하고 기다릴게) (Knock, knock, knock)
[Baby, knock, knock, knock, kno-knock on my door
Knock, knock, knock, kno-knock]
(들어도 계속 듣고 싶은 걸
Knock on my door)

[Bridge: Mina, Tzuyu, Dahyun & Jihyo]
Hey, hey, 이 시간이 지나면
굳어있던 내 맘이 내 내 맘이
Ice cream처럼 녹아 버릴 테니까
Come knock on my door, oh-oh-oh, oh

[Chorus: Nayeon, Dahyun + Chaeyoung, Jihyo, All, (Jeongyeon) & [Momo + Tzuyu]]
내 맘이 열리게 두드려줘
세게 쿵 쿵 다시 한번 쿵 쿵
Baby, knock, knock, knock, kno-knock on my door (Oh-oh)
Knock, knock, knock, kno-knock (Oh-oh)
쉽게 열리지는 않을 거야 (Oh-oh-oh-oh, say that you’re mine!)
(내일도 모레도 다시 와줘) (다시 와줘)
(준비하고 기다릴게) (Knock, knock, knock) (Baby, yeah)
[Baby, knock, knock, knock, kno-knock on my door
Knock, knock, knock, kno-knock] (Knock on my door)
들어도 계속 듣고 싶은 걸
Knock on my door (Knock on my door, oh-oh-oh, oh)

[Outro: Mina, Chaeyoung, Tzuyu & Nayeon]
Knock, knock, knock, knock on my door
(I'm freakin' freakin' out, freakin' out, out, knock knock)
Knock, knock, knock, knock on my door
Knock, knock, knock, knock on my door
Knock, knock, knock, knock, knock on my door
Knock, knock, knock, knock, knock on my door
