In the devils eye

Some teachers give detention. He gives damnation
He doesn't smile. He doesn't care. He doesn't feel.

To the students of Blackthorn Institute, Professor Jeon Jungkook is terrifying: cold, unreadable, and merciless. They don't know he's Lucifer - the fallen angel cast out of Heaven, the ruler of Hell, living in exile among the mortals he despises.

And he intends to stay that way. Unattached. Unbothered. Untouched.

Until he sees her.

A quiet girl who barely speaks.
A shadow in the back row.
Invisible to everyone - except him.

Eira has never drawn attention. Shy, soft-spoken, and with only one friend to her name, she's spent her life unnoticed. She prefers it that way. But when her eyes meet his - ancient, furious, inhuman - something cracks.

He begins to see her everywhere. Hear her voice even in silence. Feel her fear. Smell her soul.

And that soul is exactly the kind Lucifer was forbidden to ever desire.

But now he does. Obsessively.

If he touches her, he risks eternal war.
If he walks away, he risks madness.
But the Devil doesn't walk away.

Especially not from the one thing in all creation that makes him feel alive.

She should've stayed invisible.
Now she belongs to Hell.
