1989–2012: Early life and career beginnings Young was born Stephanie Young Hwang on August 1, 1989, in
San Francisco, California. Her family currently consists of her father, an older sister, and an older brother. She lived with her family, including her grandparents, who alongside her mother contributed to a mix in Korean and American culture in the household. Her mother died when she was 12 years old, and she is estranged from her father. She grew up in
Diamond Bar, California, and was inspired by K-pop artist
BoA. Encouraged by her brother, at the age of 15, Young participated in a singing contest. She was spotted by a local
SM Entertainment representative, auditioned, and was accepted as a trainee. She moved to South Korea three weeks later. and was trained at SM Entertainment for almost four years. She officially debuted as a member of South Korean girl group
Girls' Generation in August 2007. The singer adopted the stage name Tiffany, the name her mother initially wanted to name her at birth. Besides Girls' Generation, Young's early solo work mostly involved songs recorded for side projects and original soundtracks. Throughout her career, she also participated as the host for several television programs. In early 2008, Young was diagnosed with vocal nodules and had to receive medical treatment. The symptoms relapsed in 2009 and 2010 in which the singer had to take a short break from her activities.
2012–2016: Girls' Generation TTS, solo debut and controversy In December 2011–January 2012, Young debuted as a musical actress through a lead role in the Korean adaptation of musical
Fame. She played the character Carmen Diaz, a performing arts student who "hopes to rise to stardom by working tirelessly on her craft". In April 2012, a Girls' Generation subgroup named
TTS was formed with Young and fellow members
Taeyeon and
Seohyun. Their debut
EP,
Twinkle, debuted at number one on the
Gaon Album Chart and went on to become the eighth highest selling album of the year in South Korea with over 140,000 copies sold. The subgroup went on to release two more EPs:
Holler (2014) and
Dear Santa (2015). In November 2013, Young participated as a contestant in the
SBS' reality program
Fashion King Korea – a program where South Korean celebrities team up with the nation's top designers to compete in fashion challenges and missions. The singer was paired with designer Ji Il-geun and finished the program in third place. During the summer of 2015, Young began work on a solo record, with the mentality of it being the "transition into the next chapter of [her] music career." She participated in writing music since 2014, calling it "nerve-wrecking [sic] to put out music [she's] written on [her] own." Young named Girls' Generation's Taeyeon as "a big part" that helped her throughout the preparation process for the album. The two singers have been known to be best friends since Young's arrival in South Korea in 2004. The album, titled
I Just Wanna Dance, was released in May 2016, making Young the second Girls' Generation member to have a solo debut. Her album met with mixed but generally favorable reviews.
Billboards Tamar Herman called the album an "audible canvas to paint a new image for [Young]", elaborating that it "showcases [her] range as an artist." The album, having a more American influence than typical K-pop, debuted at number three on both the
Billboard World Albums Chart and South Korea's Gaon Album Chart. It sold 61,409 physical copies and was chosen by
Billboard as the seventh best K-pop album of 2016. The lead single, and title track, "I Just Wanna Dance" debuted at number 10 on both the
Billboard World Digital Songs Chart and the
Gaon Digital Chart. In June 2016, the follow-up single "Heartbreak Hotel", featuring
Simon Dominic, was released through
SM Station digital music platform. To accompany her solo releases, Young held a series of small concerts titled
Weekend during the same month. In August 2016 during the
SMTown Live concert in Tokyo, Young posted photos that involved use of the Japanese flag and
Rising Sun Flag imagery to indicate her whereabouts on her social media accounts to interact with fans. Though there was no evidence of ill-intentions, this caused heavy criticism from the Korean public as the timing coincided with
Korean Liberation Day, stirring a historical war wound sentiment. This event caused her to step down from ''
Sister's Slam Dunk'', a
KBS2 variety show that she participated in at that time. Young expressed regret for her actions in two handwritten apologies posted to her social media accounts, acknowledging her lack of history knowledge. After the controversial blunder, some media spoke out in defense of Young, while others questioned the misogyny within Korean society, arguing that it can be "unforgiving" towards a female artist while a male counterpart would not receive the same treatment if the same event had occurred. In October 2016, Young featured on the
Far East Movement single "Don't Speak" for their
Identity album. In an interview with
Billboard, the hip-hop group said that working with Young "really opened our eyes", commenting on "how versatile her range is as a singer."
