Boy group SF9 is launching a unique promotion called 'BREAK THE CAGE' to commemorate the release of their second full-length album 'TENACITY'. Through a dedicated website, fans can break wax balls shaped like cages to reveal handwritten fortune messages from SF9 members. The website also features a tab where fans can preview tracks from the second album and read love letters written by members to their fandom 'Phantasy'. SF9 debuted in October 2016 under FNC Entertainment and consists of eight members: Young Bin, In Sung, Jae Yoon, Da Won, Ju Ho, Yu Tae Yang, Hwi Young, and Chan Hee.
