[Intro: Lee Eun Sang]
Oh
La-la-la-la-la-la
Oh
Hey

[Verse 1: Lee Eun Sang]
I've been thinking of you all day
To make it through Monday to Friday
Each day took too long, yeah
You're finally coming towards me
You look amazing as always
I'm floating on a cloud
Twelve thirty, a nice lunch with you
Then we take a walk
It's already three thirty, a movie now
After that it's soon
Dark out the window
Sadness floods over me
This can't be, only when I'm with you
Time flies

[Chorus: Lee Eun Sang, YODAYOUNG, Both]
Our happy moments together
All just speed by
Back to the start, undo, again, undo
I want to rewind
Boy, you make me feel so (High)
Don't want to let you go (I don't)
Back up the time (Rewind)
To the beginning of today, undo
[Interlude: YODAYOUNG]
Oh

[Verse 2: YODAYOUNG]
Though I've been with you all day, I miss you
Monday to Friday without you
Time slows down only then, so cruelly
When we're together, fast forward
In the blink of an eye, day becomes night, no no
This day at least, undo

[Chorus: Lee Eun Sang, YODAYOUNG, Both]
Our happy moments together
All just speed by
Back to the start, undo, again, undo
I want to rewind
Boy, you make me feel so (High)
Don't want to let you go (I don't)
Back up the time (Rewind)
To the beginning of today, undo

[Bridge: Lee Eun Sang, YODAYOUNG, Both]
I'm alone again this night (Oh, this night)
Take me to your dreams at least (In your dreams)
Together forever one day (Oh, oh)
I want to stay by your side
[Chorus: Lee Eun Sang, YODAYOUNG, Both]
Our happy moments together (Yeah)
All just speed by
Back to the start, undo, again, undo (Yeah, yeah, yeah)
I want to rewind (I want to rewind)
Girl, you make me feel so (High)
Don't want to let you go (I don't)
Back up the time (Rewind)
To the beginning of today, undo
