鏡音鈴心歌詞的羅馬字母版本可能包含以下內容：
"An angel, the face in my dream
But when I wake up, I see my reflection
And there's a difference, between the two of us
Is it just in my mind?"
This is the chorus
Let me take you into the future
With me, I'll create a new world
'Cause you and I are more than we seem
It's in my heart, my soul, my dreams
And this is the verses:
We both exist, out of this world
Shadows that have found their light
Both unique, we have a choice
To walk this road alone or hold hands and dance"
