[Verse 1: Jackson]
In the dark sky
Blue stars are pouring in
I couldn't wait to see you
I suddenly rush now
Don't think about what you're gonna do
Behind those closed curtains
I want you to think about me
Baby, hear me, I'm here

[Pre-Chorus: JB, Mark]
Through the small crack
You sneaked out
The sun shines brightly on me with only a ray of light
Even the darkness becomes blind
Paint the night darker, yeah
The sky where the moon and stars have fled
The only thing we see is each other's eyes
Don't worry about anything, just open up

[Chorus: Jinyoung, Yugyeom]
Knock knock on your window
Midnight's love, love serenade
I need you in my life
I want you for my whole life
Knock knock shaking your heart
Sweet love, love serenade
Getting closer
Without anyone knowing
I'll only let you hear me all night, yeah, yeah
[Verse 2: Bambam]
Baby, I'm counting the days
That I can see you again
Want time to stop eternally like this
The best I ever had
Even when my eyes are closed I can only see you
Just trust me and follow
I promise I will never leave you alone
I'll lead you through the storm
Now spread your wings
I loved you before
Now love you more
Fly to me like a butterfly and melt me again
Tell me if you can hear me

[Verse 3: Mark]
Just like a child who tastes something sweet for the first time
I can't stop
Listen to the song
I dream about you all night long
Just the two of us, open your window
If you can't sleep for a long time
And you think of me too, yeah
Will you call my name?
Baby, tell me I'm here
[Pre-Chorus: Youngjae, Jackson]
Behind the flowing curtain
You faintly shine
A trap set up that stops me with just a shadow
Even black and white is covered in color
Bring out my senses, yeah
The sky where even the wind has fallen asleep
The only air is in each other's breath
Don't hesitate anymore, let me hear you

[Chorus: Yugyeom, Jinyoung]
Knock knock on your window
Midnight's love, love serenade
I need you in my life
I want you for my whole life
Knock knock shaking your heart
Sweet love, love serenade
Open yourself up to me
Getting closer
In our own time together yeah

[Outro: JB, Youngjae]
Knock knock on your window
Midnight's love, love serenade
I need you in my life
I want you for my whole life
Knock knock shaking your heart
Sweet love, love serenade
Open yourself up to me
Getting closer
I'll only let you hear me all night, yeah, yeah
Yeah, yeah, yeah, yeah
I'll only let you hear me all night, yeah, yeah
