[Intro]
Someday in the future, when we look back
At when you would laugh like usual at this place

[Verse 1]
Within the cruelly fast flow of time, there's something that I've been searching for
An invisible, imprisoned light in a conflicting world

[Pre-Chorus 1]
I could not be open with the person I love, the one special person
The days that have passed one-by-one affects my confusion in this period--

[Chorus 1]
Someday in the future, when we look back
At when you would laugh like usual at this place
Everyone's overlapping thoughts and feelings will form a World Line
These feelings of mutual trust won't lose to any kind of rain
For this observer of the sky, this sky is the proof of tomorrow

[Verse 2]
Dreams absolutely aren't suited for such a forever unchanged scenery
At least don't erase that day of our miracle-like meeting

[Pre-Chorus 2]
The feelings of love becoming courage is not scientific, but
There is no confusion; your words guide me to the real answer--
[Chorus 2]
That day, when we met, we were
Searching for that special something at this usual place
I know the meaning of why time casually passes by
Even with how much the two of us are separated
For this observer of the sky, this sky is the proof of tomorrow

[Bridge]
Even if we are separated, far away
We are still connected like usual at this place
The still unknown tomorrow is painfully romantic

[Pre-Chorus 1]
Someday in the future, when we look back
At when you would laugh like usual at this place
Everyone's overlapping thoughts and feelings will form a World Line
These feelings of mutual trust won't lose to any kind of rain
For this observer of the sky, this sky is the proof of tomorrow
