Han Woojin, a lab bound researcher, is a man obsessed with science. When he becomes deeply immersed in an experiment, the excitement escalates all the way from an erection to climax. His colleagues even call him “Mad Woojin” when he gets like that.

One day, Woojin hears a rumor that a dokkaebi (goblin) who grants gold lives on a nearby mountain called Deokmu Mountain. Though he does not believe in supernatural superstitions, curiosity leads him to visit the place anyway. There, he encounters a dokkaebi, Baekbaek, the god of wealth. Determined to prove Baekbaek’s existence through science, Woojin enters full Mad Woojin mode…

“I’m not interested in some stupid lumps of gold! When there’s such a lovely test subject right here in front of my eyes… ♥”
