Since I was bored, I attempted a rough translation of those lyrics. Might be wrong given that my Japanese is still rough.
==========
After changing into my newest clothes
There's something about this day that makes me want to go out
The wind might mess up my bangs, but even then it's alright
There's no change in me
We're connected by lonely nights
Though there are still secrets
Uh Yeah
Yes, those are the bonds between us
Shine, it's because you have dreams
That you can live with pride, isn't it?
We have to grow up, so we must reflect on ourselves when we end up being wilful
Shine, the me today, as well my proud future self
In order not to have regrets, believe and walk onto My Stage
Oh Yeah

Recently, I've been having clear insights
I've even made new friends and the like
That guy in the store I always go to
He sure is cool, maybe I'll end up talking to him?
Without ever coming to compromise, we end up fighting
Uh Yeah
How do we go about apologizing?
*Shine, because there is love, perhaps we can come to forgive each other?
Even if you speak negatively, good things won't happen
Shine, the world today, and join hands proudly
Believe in the words of family and walk onto My Stage
Oh Yeah

Credits to meeeeee.
It's a youthful sort of song.
But as I said, it's kind of mature!
