One day, Tae Ihyeon, the strongest being in humanity and a legendary hunter, decides to leave everything behind and become a web novel writer. However, having lived his entire life as an overpowered being, Ihyeon's novel has a critical flaw, it lacks realism. To resolve this issue, he infiltrates a C-rank guild, <Harmony of All Things>, pretending to be an F-rank hunter to conduct research. He originally joined the guild just to gather ideas for his novel, but… "Huh, this guild... I kind of like it?" As he observes the desperate struggles of low-rank hunters firsthand, he slowly grows, not just as a writer but also as a person. Can "the boy who was once a god" successfully debut as an ordinary human and writer?
