A romance fantasy always follows the same formula.

A beautiful heroine.
A flawless male lead.
And a story where love conquers all.

As a web novel PD, he’s seen it all, and he hates it.

So when he wakes up inside his sister’s cliché romance fantasy, he makes a decision:

Break the story.

Possessing a disposable extra, he abandons the script and forges a new identity,

Cain. The Empire’s Mad Dog.

No more waiting for love to solve everything.
No more tolerating incompetent “male leads.”
No more letting the world end for the sake of romance.

He hunts demons relentlessly.
Executes traitors without hesitation.
Tears apart carefully constructed relationships.

And prepares for the true threat lurking behind the story,

the Seven Deadly Sins.

As the original plot collapses and the characters begin to change, one thing becomes clear:

This is no longer a romance fantasy.

Because in a world built on love and lies,

a mad dog has taken control.
