[Verse 1: Jaehyun, Yuta, Mark, Haechan]
What are you doing now? Yeah
I can't sleep, yeah, yeah
I keep smiling whenever I think of you
This isn't a joke, yeah, yeah
I seem to have gotten excited over your voice, yeah, yeah
Without any reasons, excuses are made again
This isn't like me at all, why? Why?

[Refrain: Taeil, Taeyong]
No one knows I get drunk on my own over these fantasies
A night in which I can go into the place you deeply, deeply hide in

[Pre-Chorus: Doyoung, Jaehyun, Haechan, Taeil]
When I look at you
Like a child, I keep thinking of many small questions
I want to get to know you a little bit more
When the night comes
As if it was a daily habit, you're all I think about
I'm curious, I can't fall sleep in this night

[Chorus: Jungwoo, Mark]
On your heart I knock on, knock on, knock on
Drunk in this night, I knock on, knock on, knock on

[Verse 4: Taeyong, Johnny, Winwin & Haechan, Jungwoo, *Taeil*]
Just like a lullaby, your breath is warm
Every word you say is perfect lyricism
I want to continue listening to you, yeah
More than everyone else these days
*It seems that we have grown closer
What do you think of that? I like it*

[Refrain: Haechan, Doyoung]
After finishing the call, you'll write in your diary
I wonder if my name will be there too
I'm curious about everything regarding your day

[Pre-Chorus: Doyoung, Jaehyun, Haechan, Taeil]
When I look at you
Like a child, I keep thinking of many small questions
I want to get to know you a little bit more
When the night comes
As if it was a daily habit, you're all I think about
I'm curious, I can't fall sleep in this night

[Chorus: Jungwoo, Taeyong]
On your heart I knock on, knock on, knock on
Drunk in this night, I knock on, knock on, knock on

[Outro: Taeil]
Have a good night today too
