Hello!
I downloaded the BMS of this song (one of my favorites from SLAKE!), and one of the sound files is the main "core" of the song, without most of the samples used in-game. I heard that sample-less version, and tried to decipher some of the lyrics... I'll post below what I understood of the lyrics:
From there you looked back in lunacy
You were hung up by this love
From there you looked back in lunacy
You were hung up by this love
Love is drowing
My deeper secrets
No want to tell
Want to love
The night around me
You can be here
And I'm going
You are all we are
And you can't find
And it moved along
This moment
Felt all this feeling
And I can love
(repeat)
