On the 4th of September, a poster of MAMAMOO's HwaSa and EXO Kai taken by a Korean netizen started circulating online, leaving fans excited and overjoyed. As the pair seem to be part of a new campaign for the top health and beauty brand in South Korea called "Olive Young." The company has numerous stores all over the country and sells everything from cosmetics to medication and general health items.

Although the brand has yet to release an official statement, fans of both artists are excited about the campaign and are already wondering what the campaign or the possible brand deal will entail. Many moomoos are already sharing the clip of HwaSa from an episode of "I Live Alone," where the idol gushed about her love for the brand and the fact that she will always spend too much if she goes into one of their stores.

Other fans also began to spread possible collab or feature scenarios, many pointing to the fact that after Taeyeon and Key were selected as campaign models for "Olive Young." The female idol also featured on Key's song "Hate That' (feat. Taeyeon). Thus, hoping that if the pair are revealed as new models for the brand, there might be a collaboration between them as well. 

Although, it is not clear what the campaign will entail or when it will be officially announced. Fans of both artists are buzzing positively with excitement. They can't wait to see what the campaign will bring, especially about the possibility of a collaboration between both talented singers somewhere down the line.
