City’s breathing slow like it’s keeping our secret
Every shadow on the wall knows we’re deeper than we say
You move like midnight telling me its stories
And I follow even when the words slip away
You laugh like you’re hiding something dangerous
Soft enough to pull my guard to dust
No one knows the you I see this close
The one you keep beneath your coat of ghosts
There’s a truth in the silence you never name
A spark in the dark that feels the same
And when you turn your face my way
I feel the night bend begin to sway
誰にも見せない その影を
Just let it breathe when the lights turn low
You let your secrets fall into my hands
Like something stolen that only I can understand
今夜だけの君でいい
I’ll keep every piece where no one else can see
Behind the night behind your eyes
You show the truth you never tell in daylight
誰にも見せない その影を
Just let it breathe when the lights turn low
You let your secrets fall into my hands
Like something stolen that only I can understand
今夜だけの君でいい
I’ll keep every piece where no one else can see
Behind the night behind your eyes
You show the truth you never tell in daylight
You trace the rim of your glass like you’re drawing a map
Leading me to places you never meant to share
Your whisper bends the room into a soft collapse
And I’m slipping through the moment hanging in the air
Your voice has a color only 夜 knows
Blurred like perfume on your hidden clothes
And I taste the quiet breaking inside you
Where the past fades out and the real comes through
There’s a rhythm in the way you breathe
A subtle key meant only for me
You turn your shadows into gold
In ways you never let unfold
誰にも見せない その影を
Just let it breathe when the lights turn low
You let your secrets fall into my hands
Like something stolen that only I can understand
今夜だけの君でいい
I’ll keep every piece where no one else can see
Behind the night behind your eyes
You show the truth you never tell in daylight
Come closer
君の沈黙が語る before your lips do
I read the tension like scripture
Only written for two
If this is a sin we’re making
Then let the 夜 forgive
Your hidden self is the only place
I wanna live
誰にも見せない その影を
Let it unfold where the moon can’t glow
You let your secrets fall into my hands
Like a whispered promise only I can know
今夜だけの君でいい
I’ll guard every truth that drifts to me
Behind the night behind your eyes
You show the truth you never give to daylight

BEHIND THE NIGHT (Japanese ver)
E:SI Signature Sound
BEHIND THE NIGHT is a 3-track EP that captures the emotions left behind in the quiet moments of the night.
The title track "BEHIND THE NIGHT" reflects unspoken feelings and the solitude that surfaces after dark.
Human-crafted production blends seamlessly with AI-driven vocals, blurring the lines between intention and instinct, emotion and echo.
It's designed to slip naturally into everyday scenes-late-night walks, empty rooms, or fleeting moments shared as background music on social media.
"CaLL ME BaCK" follows as a continuation of that night, tracing uncertainty, distance, and the tension between hope and hesitation.
Its subtle groove and intimate tone make it an ideal companion for short-form videos, reels, and stories-music that supports the moment without overpowering it.
The bonus track "BEHIND THE NIGHT (Japanese ver)" reimagines the same night through a different language, offering a more introspective and personal perspective.
Hidden truths, quiet longing, and fragile wishes behind the night.
This EP is a small collection of sounds made to stay close-whether you're listening alone or letting it play behind your story.
