Tae Ihyun, known as 'Thunder Emperor' and humanity's strongest Legendary Hunter, one day decides to leave everything behind to become a web novelist.

However, having lived his entire life as an overpowered character, Ihyun's novels critically lack 'reality.' To solve this problem, he infiltrates a C-rank guild <Harmony Guild> pretending to be F-rank to conduct research.

Though he joined the guild just to get ideas for his novel, surprisingly, he thinks "This guild... I kind of like it?" As he directly observes the desperate survival stories of low-rank hunters, he gradually grows both as a human and as a writer.

Can this boy who was once a 'god' successfully debut as an ordinary human and writer?
