Sang-Woo is Based on the Director’s Past
Actor Park Hae-soo played Cho Sang-woo, one of the smartest contestants on the show. While studying the role, Hae-soo drew a great deal of inspiration from director Dong-hyuk’s personal experiences at Seoul National University since both the director and the character Sang-woo attended the same university. Another interesting tidbit about the show is that Dong-hyuk’s grandmother also worked at the Ssangmun-dong Market just like Sang-woo’s mother did on the series.
