I really love this song, and seeing that it wasn't translated yet... I had to do it. It's currently 1:50AM as I post this, so I hope the lyrics make sense.

Still inexperienced and shoddy, fragile and not enough

Small and weak, and hopeless; it’s me

I just wanted to know, success and failure; correct and incorrect:

If I were to draw the boundary line between those two, where would it be?

Well then, if I overcome my failures, my incorrect becoming correct

What would you call that? Let’s name it someday

“My dreams won’t come true”, “My hopes won’t reach”

Is that why you’ll stop walking?

“Effort is not rewarded”, “No one will recognize”

Is that why you’ll stop running?

Will you stop?

If it’s reasons why I want to give up, there’s 10, 100, 1000 of them

But all of those seemed tiny because of one thing

If it’s words to use to run away, they’ve come up so much that I’ve gotten tired

But there was a brilliance that just wouldn’t let that show

I just wanted to know, for today and tomorrow’s

Boundary line between adult and child, if I were to draw it, where would it be?

Everyone says they want to be that when they grow up

Well, I wonder if I can do anything, the me of today

Three years ago, the excuse that someone threw into the evening sky

I’ve already forgotten it, they’re useless words

Let’s hum it as a song someday

There is not guidepost, no one will tell me

Because our footprints joined together, we were able to meet

If it’s the nights I wanted to break, there’s 10, 100, 1000 of them

But I had the wings to fly over all of it

Where does the story that started that day go?

The me starting from tomorrow seems to have more homework assigned

I started with one horizontal line, the us from that day is already gone

The place you’re heading, the place I’m heading, neither of them are necessary

Beyond the number of setbacks, beyond the number of winters

Like how the flower opens, like how the blue gems shine

I found it because it was so bright, I couldn’t help it

That shine’s true colors…

If it’s reasons why I want to give up, there’s 10, 100, 1000 of them

But all of those seemed tiny because of one thing

We are ahead of the story that began that day

Illuminate together, the lights we found, let’s check our answers

There’s just one thing to draw just as one likes

It’s the blue sparking moment
