Gain
Gain (가인), born Son Ga-in (손가인) on September 20, 1987, is a South Korean singer and actress. She is best known as the maknae of the acclaimed girl group Brown Eyed Girls, which debuted in March 2006 under Nega Network. Gain entered the group after catching the attention of composer Ahn Jung-hoon during a reality audition, and quickly became a fan favourite for her magnetic stage presence.
The group’s 2009 breakthrough with “Abracadabra” opened the door to Gain’s solo career. Her debut EP Step 2/4 (2010) featured the tango-infused title track “Irreversible,” which topped the Gaon Digital Chart and positioned her as one of K-pop’s boldest solo voices. Subsequent releases pushed further: “Bloom” (2012) became a defining statement on sensuality, while “FxxK U” (2014, featuring Bumkey) blended hip-hop and R&B into a chart hit. Her Hawwah EP (2016) and Suspect X EP (2021) extended a solo career defined by creative courage and refusal to play it safe.
Gain also appeared on We Got Married with Jo Kwon, forming one of the show’s most beloved virtual couples, and collaborated on the digital single “We Fell in Love” which spent three weeks at the top of the Gaon Digital Chart. In December 2025, Gain and Jo Kwon released an updated version of the track as a ten-year anniversary gift to fans. She is currently signed to APOP Entertainment.
