Who is Suhyeon (Billlie)?

Suhyeon (수현), born Kim Su-hyun (김수현), is a South Korean actress, singer, and lyricist under MYSTIC STORY. She serves as a member of the girl group Billlie, which debuted on November 10, 2021, with the mini album The Billage of Perception: Chapter One.

Born on January 15, 2000, in Bisan-dong, Seo-gu, Daegu, South Korea, Suhyeon stands 162 cm tall with blood type O. She has been active in the entertainment industry since 2016, initially gaining recognition through her participation in survival programs. Specifically, she competed on Mnet's Produce 101, where she ranked 69th and was eliminated in episode 5. She later became a contestant on JTBC's MIXNINE in October 2017, reaching the final episode before elimination when the boys' team won against the girls' team.

Her acting career began in 2017 with the drama Girls' Generation 1979. She subsequently starred in the web drama A-Teen in 2018 and its 2019 sequel A-Teen 2.

Suhyeon's early career and survival shows

Produce 101 appearance

Representing MYSTIC Story (then MYSTIC Entertainment), she competed on Mnet's survival reality program Produce 101 in 2016. Her elimination occurred in the show's fifth episode with a final placement of 69th. Following the Mnet vote manipulation investigation conducted in 2019, authorities revealed that she was one of two Season 1 contestants victimized by vote manipulation. The votes presented during the fifth episode were lower than the actual number she received, resulting in an unfair elimination. The true vote count and her actual ranking in that episode remain undisclosed.

MIXNINE participation

In October 2017, she joined JTBC's survival program MIXNINE, again representing MYSTIC Story. She advanced through the competition until the final episode, where she achieved 17th place. Her elimination resulted from the boys' team victory over the girls' team, which prevented the female contestants from debuting despite reaching the finale. During the show's first mission, she performed "Boombayah" alongside Ryujin (ITZY) and Siyeon (Dreamcatcher), serving as center, main vocalist, and lead rapper for the stage.
