Returned by the King

In a world where one's worth is determined by how powerful their skill is, Taehyeon is 35, unawakened, and barely able to scrape by as a pack bearer for monster hunters. But when a mysterious being calling itself the King gives him a skill of his own, Taehyeon gets a second chance at life. Now he’s back in high school and armed with Gluttony, a skill that allows him to block and absorb the skills of others!
