我们约好在下雨天，你却让我独自等待
Verse 1:
Grey skies, rain falls
I'm waiting alone, against these walls
We made a plan, you and I
But you never came, and I don't know why

Chorus:
We said we'd meet, on this rainy day
But you left me here, to wait in dismay
I don't understand, what went wrong
You left me here, waiting so long

Verse 2:
My heart's beating fast, in this cold rain
I'm losing hope, that you'll come again
My mind is racing, with thoughts of you
I don't know what to do

Chorus:
We said we'd meet, on this rainy day
But you left me here, to wait in dismay
I don't understand, what went wrong
You left me here, waiting so long

Bridge:
I'm standing here, getting soaked through
Wondering if you're missing me too
I thought we had something special
But now I feel so alone and vulnerable

Chorus:
We said we'd meet, on this rainy day
But you left me here, to wait in dismay
I don't understand, what went wrong
You left me here, waiting so long

Outro:
The rain keeps falling, it won't stop
But my tears have dried up
I'm moving on, from this pain
I won't wait for you again.
