A world ruined by a plague with no cure.

With the fall of government and law, the world has become a living hell.

High above the wrecked world stood a steep, forbidding mountain range—so treacherous that no one dared to climb it. Hidden deep within those peaks was a haven, a safe and cozy home.

There, Yeonwoo lived peacefully with her two fathers, and Berry, a former stray—both of whom cherished and protected her. It was a life of quiet happiness that seemed like it would last forever.

But that peace shattered with the arrival of a mysterious “guest.”

In front of the flames that devoured her family and home, Yeonwoo stood frozen in shock.

Then came a voice—unfamiliar, from behind her.

“Do you live here?”

What fate awaits Yeonwoo after her encounter with Barkley, the blue-eyed survivor who conquered hell itself?
