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.

Silvia was smiling on the outside, but it was extremely easy for Keith to tell that she was pissed by just looking at her eyes.

"It's fine. I've heard that you dance really well so I hope that the rumors are true." she said as she gave him her hand.

Keith stared at the small, delicate hand for two whole seconds before taking it, "Of course, my princess." he said before giving her a bright smile.

He then laced his fingers with her other hand and pulled her close, "I hope you can keep up with me." he whispered as he looked at the few people who were now hurrying towards the musical instruments.

"I've already picked a side and it's a pity that I'll have to go against you in the future." he continued while the princess was way too busy sniffing him.

"What the hell are you doing?" he asked but she simply looked up with half lidded eyes, "You smell nice..."

".... get a hold of yourself. There's others watching."
