One reason的歌詞如下：
歌名：One reason
You were a cloud
That would follow me everywhere
Through the city lights and alleys of rain
And every memory you would fill with grace
You were the scenery
Of every song that I sang
And every melody was a memory of your name
But now you're just one reason why
I'm feeling blue tonight
One reason why I'm feeling blue tonight
It's not the end of the world
But it's not the start of a new beginning
It's just one reason why I miss you
And I don't know why
You were my favorite melody
In a symphony of love songs
And every note was a memory of your touch
But now you're just one reason why
I'm feeling blue tonight
One reason why I'm feeling blue tonight
It's not the end of the world
But it's not the start of a new beginning
It's just one reason why I miss you
And I don't know why
It was only a matter of time
Before it all began to fade
But I can't help but wonder what could have been
And it doesn't seem fair that you're not here
Now I realize that every memory was real
And now that it's all fading away
I don't know what to say
One reason why I'm feeling blue tonight
And it's not the end of the world
But it's not the start of a new beginning
It's just one reason why I miss you
And I don't know why
I don't know why.
