{English translation}
I was standing around on the narrow street
when those indifferent words grazed by me
Hello, hello
Unfamiliar but not awkward, it felt nice
Would it be okay to lean on you?
With concern, that wrinkled sincerity unfolds in front of me
Thank you, thank you
Conveying my simple, thankful honesty
That's true
Hello, hello, my cute angel
Stay by my side always
Also
Thank you, thank you
That's what I want to tell you
No no no no no
Just the words thank you
It's not easy to be deliberately wrong
because the more you do, the more you'll regret enduring it
I know, I know
Maybe it's better for that smiling Pierrot
Would I be able to stand up without becoming dirtied?
Though I brush myself off, the pain builds
She knows, she knows
No longer is tomorrow only mine
The world I've confronted so many times
You've taught me to greet it
My heart overflows with this melody
I'll go on together with you
That's true
Hello, hello, my cute angel
Stay by my side always
Also
Thank you, thank you
That's what I want to tell you
No no no no no
More than a love confession
The words thank you
convey all my feelings
