Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth,  was slightly different. 

People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel's world, he was also given a mystical ability to grant systems to other people. 

Armed with his special ability, he slowly climbs up the power ladder by taking "taxes" from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.

He stood on top of the tea table with a newspaper in hand while the rest were laughing like crazy.

"-h nooo, I want to see my baby! I will kill that dog of a prince if I get an opportunity, ahhhh. Oh Keith, you're here." he said and jumped off the table.

Keith nodded and faced the middle aged man in front of him whose hair seemed to have started to turn grey due to age. He bowed slightly and introduced himself.

"It's a pleasure to meet you, Duke Arthur Toretto. On behalf of my team, I thank you for your hospitality."

The guy waved his hand nonchalantly, "Don't bother with all that stuff. I'm already tired of keeping appearances in front of the others and I don't wanna do it with everyone I see. Just talk to me normally."

He then turned to look at the butler, who in turned shifted his gaze towards a servant who was standing at one corner.

The guy immediately bowed low, hitting 90 degrees before standing back up, "I'll bring extra chairs."
