Hello, this song should be: Gray Space, Luo Zhixiang has covered it, but there is also a female humming version, the lyrics are as follows:

"Gray Space"

Lyricist: Yao Ruolong

Composer: Yoo/Young Seok

Arranger: Chen Feiwu

Singer: Luo Zhixiang

It turns out it’s not Bai It’s just black

It’s just a naive belief

To be drunk and sober is to commit an innocent crime

The real world is only gray

Be strong I feel so tired after being here for so long

I want to hug the one I love and fall into a deep sleep

There is beauty in the fierceness of the storm

I don’t feel the heartache when I die

Who am I in the gray space

Can’t remember what happiness feels like

Who are you with no way out

How can you shed tears for me

Dreaming of the glowing grassland

Going back to a long time ago with an injury

I choose not to hate walking away with peace

Wake up The night will be long after coming

Hold me tight and cry
