Somin

On September 5, 2012, Somin debuted in the girl group PURETTY, a group based in Japan, with plans to debut in South Korea as well. The group effectively disbanded in May 2014 after it was announced that she, along with her fellow members Chaekyung and Shiyoon, would participated in KARA Project, a show which aimed to find new members for the girl group KARA. Somin finished the show in second place, ultimately being eliminated.

On August 24, 2015, she debuted again, now as the leader of the girl group APRIL. But her career with the group was short, she left in November that year to pursue a solo career. In 2016, she became a member of the co-ed group KARD.
