On December 21, agency Fantagio revealed, "Seo Kang Jun will be appearing in the MV of Hello Venus, which plans to make a comeback in January. The format is not that of a drama. Seo Kang Jun and all of Hello Venus will appear. The filming is planned for next week."
This isn't their first time working together as he previously appeared in their MV for "Do You Want Some Tea" back in 2013.
