Awakened

Jeon Jungkook's life is already a horror movie.

He's 28, a broke Psychology professor whose HOD hates him, whose step-family uses him like an ATM, and whose neighbors include:

Jin - who tells dad jokes and then goes WHEEZEK like a broken kettle.
Jimin - who tells a joke, stares at you for 10 seconds, then yells "THAT WAS THE PUNCHLINE!"
And Yoongi - the local mafia who is asleep 22 hours a day but will wake up just to threaten anyone who bothers Jungkook.

It couldn't get worse. Until Jungkook accidentally swallows a 500-year-old artefact that opens the Doors of Hell.

Now his glasses glow, his books float, and a demon lives rent-free in his chest.

And Kim Taehyung - rich, gorgeous, lazy conglomerate heir from a family of Guardians - is ordered to move in with him and suppress it.

"I don't want to guard you, you annoy me."
"Then leave my apartment!"
"Can't. You'll literally end the world if I do."
