The Gamer

Han Jee-Han, a normal high school student, suddenly develops a special power where his entire world is shifted into a game-like setting. He can see the power levels of people, look at the stats of a seemingly normal item, get abilities, and even level up! Follow Han Jee-Han as he discovers how to use this power, and maybe even where it came from.
