Translation:

Song of Spring

I [bad word] to a muddy road with heavy feet
I [bad word] through the bushes with thorns
I ate everything that I could have eaten

As I went through a long tunnel
I was shrouded by unfamiliar colors
It was at that place that everything begun

"It doesn't matter."
I kept such a stained word inside me
Now i'll shoot my own heart

The song of spring
Echoing before love and hope
Can you hear me?
Even you are reflected in the distant sky

It's quite impossible to keep a straight face
I smiled so hard that I wanted to cry
As we exposed ourselves to the morning light

Things that I had forgotten
But I really didn't want to forget them
So i'll write your name down

The song of spring
Creating love for the first time
Don't [bad word] it
This road that goes wherever

Let's keep walking
The monkey remains alone
This is not an illusion
Let's keep walking

The song of spring
Echoing before love and hope
Can you hear me?
Even you are reflected in the distant sky

The song of spring
Creating love for the first time
Don't [bad word] it
This road that goes wherever
