He was summoned to save the world… but his greatest threat isn’t the Demon King — it’s the women who love him.Kai Veyron was just a delivery guy on Earth. But in the magical world of Aethria, he’s “The Chosen Hero” — gifted with ridiculous, godlike powers that he can’t control and didn’t ask for. He defeats monsters by sneezing, trips over relics that explode, and somehow charms every powerful woman he meets.Now surrounded by a beautiful, deadly harem — a tsundere princess, a cold-blooded assassin, a genius mage, a seductive demoness, and a broken childhood friend — Kai thinks he’s finally found purpose, friendship… maybe even love.But peace has a price.As whispers of prophecy grow louder, the women begin to ask the unthinkable:“What if the hero himself is the final calamity?”They laugh with him by day… and plot his death by night.And the worst part?Kai already knows.And he still protects them — even if it means his own downfall.

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.
