Where is this warmth going?
When it’s tomorrow, it’ll vanish
If I synchronized the heartbeats of our chests
Would I be able to fall to the same depth as you?

I’m always, always by your side
No matter how far your heart strays

While we drift inside the darkness
Like innocent little birds, we huddled our wings together
You, who hide behind your smile when you’re lonely
Are a blade of unmelting ice
I bare my heart
And embrace you
Forever…

Where are you going alone?
I’m just scared of looking back
The figure in my chest and the sad color
Even though I’m sure that they’re actually very similar

With the same evanescence, we are gazing
At the place that we’ll surely return to someday

No matter how we’re separated inside this darkness
Our hearts call for each other with a bond stronger than anything
Even if you’re laughing when you’re lonely, I know it
I want to warm
Your cold fingers with my tears
I’m by your side…

While we drift inside the darkness
Like innocent little birds, we huddled our wings together
You, who hide behind your smile when you’re lonely
Are a blade of unmelting ice
I bare my heart and embrace you
I’m by your side
Forever…
