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.

If you have any corrections, feel free to tell me!

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
