After taking in her mother’s najin at the end of Season 1, Yoon Chae-ok (Han So-hee) continues her line of work as a private eye who tracks down missing people—only now she’s gifted with immortality and superhuman strength, speed and agility thanks to the najin. She runs into Jang Ho-jae (Park Seo-joon), who bears a striking resemblance to Jang Tae-sang, the pawnbroker from 1940s Gyeongseong that she fell in love with. Of course, that’s because Ho-jae is Tae-sang—it’s just that he’s lost his memory when Chae-ok encounters him in the streets of Seoul.
