Halo under Guard

Heeseon is the idol everyone adores-soft smile, angelic voice, untouchable purity.
What the world doesn't know?
He was never human to begin with.
Hiding in plain sight, Heeseon is a real angel living among mortals... and someone is hunting him.
Assigned to protect him is Baek Ryujin-a demon with a reputation for being cold, ruthless, and impossible to break. Silent. Dominant. Deadly. Bound by contract and hellfire, Ryujin is meant to be nothing more than a shield.
But angels aren't supposed to look at demons like that.
And demons aren't supposed to fall Between late-night dorms, whispered confessions at 3AM, idol scandals, and attacks lurking in the shadows, the line between protector and something more begins to blur. Every almost-touch is dangerous. Every choice could cost them everything.
When Heaven demands obedience and Hell demands sacrifice, Heeseon must decide: ascend and be safe... or stay and fight for the demon who guards his heart.
