On Guard

[Verse 1]
There's a black hole at the window
Howling at any change in the air
If you forget to lock your smile in
Don't you worry, the sorrow will be there

[Chorus]
So I remain on guard

[Verse 2]
Old habits dig their roots in
Dark slivers of past everywhere
I remember I've been hiding something
But seems I forgot how to share

[Chorus]
So I remain on guard

[Verse 3]
And I hope you will not hurt me
That what you don't say is also true
You know, I want so much to trust you
To hand over my heart like it's new

[Chorus]
But I remain on guard
