Author and Illustrator

She recently wrote a book, "Tango" (탱고), about the love story of a girl who falls in love with three men. The book received good reviews and many critics praised her for her well-structured sentences. This book is currently a bestseller, selling 30,000 copies within one week. She also illustrated the cover of Gummy's Album which was released in 2008.


Singer

She sang "Saranga" which became the title song of the Pure in Heart drama, and Shim Soo Bong's "I Don't Know Anything But Love" in Boys Over Flowers. She also did a duet of Kim Gun Mo's "Rain Falls on a Sleepless Night" with Big Bang member Seungri on talk show Peppermint on March 7, 2009.

She was originally supposed to debut in a group with 2NE1's Sandara Park and Park Bom, but now prepares to release a solo album. In Episode 4 of 2NE1TV, they were shown visiting fellow YG Entertainment colleague, Koo Hye Sun's art exhibition. Park Bom revealed on the show, "Back in 2005, Koo Hye Sun, Sandara Park, and I [Park Bom] joined YG and were told that we were going to become a three-member girl group."

Koo had been preparing for her album for a while, but the album release date was pushed back because of her book Tango and her art exhibition. She will be receiving help from 1tym members Oh Jin Hwan and Song Baek Kyung, and Tablo for her upcoming album. Her first album will include OSTs of her Full-Length Movie and is slated to release in Fall 2009.
