Obsessed lab hermit Han Woojin has a scandalous secret: his passion for science is literal. When he hits a breakthrough, his body reacts with an uncontrollable, physical intensity that has earned him the nickname Mad Woojin. Driven by cold logic, he treks to Deokmu Mountain to debunk rumors of a gold-granting goblin. Instead, he finds Baekbaek, a breathtaking god of wealth. Forget the gold, Woojin has found the ultimate specimen...and he's ready to experiment until they both reach their limit. (Source: Lezhin Entertainment)
