Translation:

Even though it is easy for me to cry 
They do not flow of sadness 
This separation 
From those I held dear 
Was solely 
My decision

Like a bird that strays away from its flock 
I do not know where my destination lies 
But no matter if I get hurt 
And scar till my blood flows 
My heart will always remain 
Just soaring

This bluebird 
Even if happiness 
Is close by 
I shall fly 
Towards the sky 
And believe in my future 
I will not forget you 
But I cannot ever turn back to yesterday

Than watching the glittering sea from the window 
I would rather plunge myself into its waves 
So let go 
Of your hand 
That is stopping me from 
Going to that somewhere I have to go

We spent some sweet times together 
Inside the birdcage that you carry 
But now I must go 
In search of the red [bad word] 
Even though someday 
I will be saddened of this parting

This bluebird 
With freedom and solitude 
As its pair of wings 
I shall fly 
Towards the sky 
On a journey for my distant dreams 
These wings I have chosen is because 
I needed to go and live my life

This bluebird 
Even if happiness 
Is close by 
I shall sing my song 
Up above the sky 
And face my future 
I had loved you 
But I will only be looking on forward
