You're standing in front of that door and you think.
Once it's open, there's no going back.
Everything may fall apart.
But if we don't step out now, there's no point
Because one day we'll disappear
Because the future is uncertain and fleeting
I have to convey my overflowing feelings now
To the one you love in front of you.
The moment we're born, we're sure to...
The moment we were born, we must have cried because we knew the meaning of this journey.
We cried because we knew we'd be alone at the end.
Why do we want to be close to each other?
Behind that door...
Have you finally found it?
Because one day we will disappear
Because the future is uncertain and fleeting
I have to tell my overflowing feelings now
To the one you love in front of you
Even if you don't get the answer you want
Even if deep sadness awaits you
If you want to be sure, then be brave
In that moment, the world will change
The pulsating heartbeat tells us
What we're really looking for
Is the heart to love someone else
In this moment, we are alive
Come on, knock on the door
