Soo-hyun, a kind-hearted flight attendant with a thirst for quiet adventure, has always believed the sky was the safest escape from the chaos of life. Serving coffee at 30,000 feet, she never imagined danger would board her flight—until it did.

Ji-hyun is no ordinary passenger. A ruthless businessman hiding a dark past as one of Seoul’s most feared mafia leaders, he boards the plane bleeding, hunted, and out of options.

When Soo-hyun chooses to help him instead of turning him in, she is pulled into a shadowy world of secrets, betrayal, and power. As the line between duty and desire blurs, Soo-hyun must decide: will she return to the safety of the skies—or fall with him into the darkness?

Two strangers. One flight. A collision of fate that could either save them... or destroy them both.

There is a strange silence that exists only in the sky. 


A space where secrets sleep above the clouds, and fates collide in the quiet hum of engines.


For Soo-hyun, the sky was freedom. Her escape.


But freedom ends when danger takes the window seat.


He came with blood on his shirt and shadows in his eyes.


Ji-hyun a name whispered in the underworld, feared in boardrooms, and now... leaning against her cart, asking for mercy in midair.


Because even in the clouds, darkness can find you.
