Fin.K.L debuted in 1998 and quickly became popular, catapulting all its members into stardom.

Starting her solo career in summer of 2003, Ock came out with a ballad called "난..." ("Nan...", meaning "I..."), which entered the top 10 of Korea's music charts. By her second album, which came out in the fall of 2004, the public was startled by the sudden change in appearance, as she had experienced a significant weight loss; Ock attributed to her intense yoga training.

Her third album, titled Remind
, was released on June 12, 2008. The first single off the album is "Honey", which is a departure from her previous singles as it incorporates R&B. She began her comeback performances the following weekend on the major music shows.
Her next album is due in mid-2009.
