She is a Korean singer, actress, model, MC and musical actress. She first debuted in 2001 under SM Entertainment, releasing two solo albums before being included in a 4-member-group called CSJH The Grace (천상지희 Cheon Sang Ji Hui / 天上智喜 Tenjochiki in Japan) in 2005.
The group halted its activity soon after the release of the second Japanese full album in 2009.
Despite that, in 2011 she came back as a member of the group's sub-unit "CSJH Dana & Sunday" with fellow groupmate Sunday. They released a digital single that year.
She's currently focusing on her solo career as a musical actress. Some of her most successful performances include "Peter Pan", "The Three Musketeers", "Bonnie and Clyde", "Catch Me If You Can".
