I Became the S-Class Guide for the Obsessive Madman

I’ve been transmigrated into an R-rated, tragic guide-verse BL novel.

And into a world where an obsessive madman destroys the empire.

ab*sed by a guide in his childhood, he turns dark and grows up to be a mad duke.

What would happen if I provided proper guidance to this obsessive man?

Of course, I should do it as an S-class guide, but…

“If you want to live, try to pique my interest.”

He inhaled deeply at the nape of my neck, as if trying to imprint my scent.

“I might help you if I see you struggling, hmm?”

Why is this obsessive man, who should be fixated on the bottom character,

showing obsession toward me, a mere extra!

I only dreamed of a safe future,

but now my life is being threatened.
