Lee Chae-yeon

Having passed an audition held by an entertainment management company in Japan, Lee first appeared on a show called Uchan Nanchan no Urinari [ja] (ウッチャンナンチャンのウリナリ!!)

[citation needed] Her debut song "위험한 연출" ("Dangerous Directing") did well, but her real success came when her second album released late in 2004.

[citation needed] The music video for "Two of Us" was controversial for being too "racy" in conservative Korea, as it contained scenes showing her full back and exposed underwear.

The record company then quickly switched to the "Disco Mix" of the song, which helped sustain its life on the charts, although not by much.

However, this can be attributed to the fade of sexy R&B music in Korea at the time, as ballads were once again the style of choice for Korean singers.

She ended her official schedule with her last X-Man episode on September 25, 2005, to concentrate on recording her fourth album.

The single was extensively performed, with a remix promoted from May onwards; she then followed up with "Clumsy Love (서투른 사랑)".

[4] In addition to promoting her album, Lee joined the cast of Hi-Five, part of KBS's Happy Sunday line-up.

Later that year, she drew media attention with her investment into, and direct involvement with Bequem, a fashion company.

Continuing to stay within the "sexy singer" concept, the lead single "Shake (Heundeullyeo)" is an electronic dance song.

[5] The music video was labelled by major networks to be unfit for broadcast without parental advisory warnings.
