This song delicately paints emotions swaying between night and morning with intricate sound design.

Created by Korean music producer TAK, featuring singer-songwriter asmi, it entrusts the wavering feelings between loss and rebirth to the image of a “reversed moon.” The moment when the urge to cling to a crimson-stained night intersects with the will to step into a blue morning is rendered three-dimensionally through precise sonic craftsmanship.

And asmi’s gentle yet resolute vocals are simply wonderful.

It’s a track you’ll want to play on sleepless nights.

The lyrics express a desire to cherish those fleeting moments when paths cross, even if we can’t fully understand one another—an idea that resonates with YUKI’s own words that the immersive experiences of reading and music are alike.
