Girl group Rainbow made special cameo appearances in an episode of SBS's "Daemul", set to air on October 20th. In the episode, Seo Hyelim (Go Hyun Jung) announces that she will be running for the National Assembly. Despite the fact that her campaign is going through a slump, she promises to emerge victorious against her rival, Kim Hyun Kap. However, representative Jo Bae Ho begins to support Kim Hyun Kap in order to push Hyelim out of the running. Jo decides to bring in Rainbow with the hopes of capturing attention in the campaign rally. Rainbow appears on-set with cosmos flowers in their hair and greets Hyelim lightly. Feeling the excitement of Rainbow's appearance, Hyelim begins showing off a gag dance and starts off the rally on a fun note. At the studio, Rainbow said, "No matter how busy we are, we always make sure to watch every episode of 'Dae Mul.' We especially love Kwon Sang Woo's character."
