The Player That Can't Level Up

Kim Gi-Gyu awakened as a player at the age of 18. He thought his life was on track towards success, climbing the tower and closing the gates... But, even after clearing the tutorial, he was level 1. He killed a goblin a day, and he was still level 1. Even after 5 years, he was still level 1. "Who would have thought that this kind of player would exist." No one knew.
