Summary
Iruma Suzuki just wanted to earn some extra money. But when he publishes "Eternal Roses" under the pen name Blue Moon, he accidentally sparks an obsession across the entire Netherworld.
His story, a dark romance filled with tension and restrained desire, becomes an unstoppable phenomenon. No one has ever experienced this kind of passion before… and now, everyone craves it.
The problem is, no one knows he’s the author.
As his work spreads among friends, teachers, and demons alike, Iruma must survive the chaos of his secret teetering on the edge of discovery… and a world that demands more.
Because in the Netherworld, desire isn’t just read.
It is consumed. -

Summary
Iruma always had a strange way of smiling, even when the white of his clothes ceased to be white.
Sabro had never understood the value of a flower until he found his own fingers stained, holding onto something he didn't know whether to release or devour.
In the end, it wasn't the law that stopped him.It was the ring of a bell and the realization that a predator is only free until he finds something worth losing his claws for.

Summary
Babyls functions because someone keeps the beast under control.
A leader who learned to smile before he learned to bite.
A pack that understands silence better than orders.
And an instinct that never stopped watching from the shadows.Power here is not proclaimed—it is sensed. Respected. Feared.
When calm begins to tighten, it is not a sign of peace, but of restraint.Because in Babyls, violence does not vanish.
It sleeps beneath antlers and fangs, waiting to be allowed to wake. -
