The MBC series starring So Ji Sub, Jung In Sun, Son Ho Joon, Lim Se Mi, UNIQ's Sungjoo, and more tells the story of a legendary black spy, and a normal woman who lives across the street. One day out of the blue, she unexpectedly becomes involved in dangerous spy affairs just because of her neighbor. 

The ritual offering was held this past August 9 at MBC, just before the cast's first set filming in Korea. Previously, the cast and staff of 'Tereus Behind Me' visited Poland for overseas filming.
