Change my life! Oh my precious days...

That's right, the future will surely
always wait for us
That's how we'll live our lives
Everyone is boarding the train
that carries fate and is heading into tomorrow

When you're running and your hand grabs the door
What are you thinking?
You hear a voice saying
"Go on and don't give up"

Don't give up Someday!
If you turn around One Day!
The passion from that time
stirrs up in your heart
It's staring Someday!
Surely, if you open the door to a new impulse
You can still go further
Beyond your smile

Change my life! Oh my precious days...

That's right, we always know
about the important power of belief
If you search for the truth,
It'll float right in front of your eyes
Let's embrace this passion and go on

In these wavering times, even if I feel sadness
in this harsh world, I have to keep moving or
nothing will change

Without hesitating, Someday!
Turn to face it One day!
There will surely come a day
when sadness and darkness will be lifted
It's starting Someday!
If you open the next door
to a new excitement
You can still go further
Beyond your wishes

Don't give up Someday!
If you turn around One Day!
The passion from that time
stirrs up in your heart
It's staring Someday!
Surely, if you open the door to a new impulse
You can still go further
Beyond your smile
