I recommend "The Rebirth of Trash: The Arrogant Specter". The male protagonist was physically and mentally clean. He had the elements of a hot-blooded academy and a doting and refreshing culture. At the same time, he had the charm of a western magic. In the alternate world, the male protagonist was a good-for-nothing, but he had the forbidden undead magic ability. He lived a leisurely life, making money by concocting pills, and bullying others by taming beasts. He could not complain about the fact that he was torturing cannon fodder, but his life did not seem to be as peaceful as he had imagined. I hope you like this fairy's recommendation. Muah ~π
