Their story
Out of The Fan
BIBI first caught attention in 2018 on The Fan, an SBS audition show. She signed with Feel Ghood Music, the label run by Tiger JK, and released her first single, "BINU", in May 2019. A string of singles followed. Her voice reminded people of IU, but the songs went somewhere much darker, and the nickname "IU in the Dark" stuck.
Lowlife princess
Her second EP, Life is a Bi..., came out in April 2021, led by "BAD SAD AND MAD", mellow R&B with glassy synths over a trap beat. Later that year she sang on "The Weekend" for 88rising. In November 2022 she put out her first studio album, Lowlife Princess: Noir, and kept moving between music and acting.
A borrowed waltz
Her biggest hit is a song she did not write. Chang Kiha gave her "Bam Yang Gang", a breakup song under two and a half minutes with a melody that sways like a waltz, written as an answer to his own band's "Side by Side". Released in February 2024 with the sultrier "Sugar Rush", it climbed for two weeks and held the top of the charts even after IU released a new song with V of BTS. In March it won her a first music show trophy.
Where she is now
EVE:ROMANCE, her second studio album, arrived in May 2025, and she wrote, composed and produced all of it. Two days later she opened her first world tour, EVE, at Olympic Hall in Seoul, then took it through North America, Asia and Oceania. In May 2026 her label signed a global partnership with Warner Music Korea, and the next day came "BUMPA", a summer song with Latin and Caribbean rhythms that she wrote and composed herself.
