There are at least 2 groups called Secret: - 1) Secret (시크릿) was a four-member South Korean girl group formed in 2009 by TS Entertainment. The group consisted of Hyosung (전효성), Jieun (송지은), Hana (정하나) and Sunhwa (한선화). Secret was first introduced through a documentary program titled Secret Story which aired on Mnet. The program chronicled their debut process and aired their invitation only debut show case which took place on September 29, 2009. The MV for their debut digital single "I Want You Back" was released on October 13, 2009 and they appeared on M! Countdown for their debut performance on October 15, 2009. Secret gained popularity after their debut appearance due to their polished vocals and stage presence; the group quickly hit the #1 searched phrase on various online portal sites. The group released 11 singles: "I Want You Back" in 2009, "Magic" and "Madonna" in 2010, "Shy Boy ", "별빛달빛" and "사랑은 MOVE" in 2011, "POISON" and "TALK THAT" in 2012, "YooHoo" and "I Do I Do" in 2013 and "I'm In Love" in 2014. On October 13, 2016, Sunhwa's contract with TS Entertainment was terminated after she decided not to renew and she left the group to pursue a career in acting. After several legal disputes regarding violations of contracts terms between TS Entertainment and members Hyosung and Jieun, both members left the company and the group was effectively disbanded in early 2018 - as Hana was the only member left. 2) Secret is a melodic rock project born in Murcia (Spain) in 2012. The line-up comprises of vocalist Jesus Espin (ex-91 Suite) (vocals and backing vocals) and guitarist Ivan Gonzalez (also ex-91 Suite) (guitars, bass, drums and keyboards). After a period of musical inactivity, and given the friendship between them, the pair decided to once again join forces with the idea of just to have "a good time making music they like". From there the pair wrote a number of new songs and the idea formed to complete an album. Finally, the project is realized under the name of Secret and the album titled The End Of The Road.
