Michelle Yim
TVB's 2007 series, "Heart of Greed", was successful enough to commission this series. In June 2007, Louise Lee presented on the Heart of Greed (溏心) chatroom that the producers had already begun to write another series with the same actors but a different story line. Details about the new series were leaked by the media in October 2007 and Lau Kar Ho, the director, writer and producer of the series, vowed to catch the person who leaked this information because few people knew about the new series. The sales presentation clip was released on 19 November 2007. The clip gave clues about the new series which featured Michelle Yim as the new villain and a mooncake business instead of the abalone business in "Heart of Greed". New cast members included Kate Tsui, Lee Heung Kam, Vincent Wan and Wayne Lai.
