Lyrics:
Verse 1
On bright screens, the numbers lean like weather
A quiet shift you barely feel at first
More men in the lines where futures gather
A balance tilting under every birth
Pre-Chorus
It isn’t one loud moment, it’s a slow delay
A different kind of missing in the crowd
When the odds rearrange what love can pay
The hush gets heavier, but not a sound
Chorus
After the crossover, hearts don’t match the charts
A widening shadow where the chances start
When the surplus lingers, someone’s left apart
So we rewrite the reasons, not the hope in us
Verse 2
Years stack up like papers on the table
A model hums, translating gaps in age
Where she can count the births, he’s less observable
But patterns still come through the turning page
Bridge
Don’t call it fate—call it choices in the light
Call it laws, and care, and dignity
Let every child be wanted, every life have room at night
Let the lonely have a hand to hold, a place to be
Final Chorus
After the crossover, hearts don’t match the charts
A widening shadow where the chances start
When the surplus lingers, someone’s left apart
So we steady the balance, with our hands and open doors
And we keep the future human—more and more
