He barely survived the chaotic first moments of the new world thanks to his knowledge of the story, but the cruel Scenarios give him no time for rest. Isolated from his group and surrounded by horrific creatures, things look grim for Dokja...until an extraordinary presence approaches. It's time for the only reader of TWSA to meet its protagonist-the Regressor Junghyeok Yu!
