Kiss (stylized as KISS.) was a Korean female pop trio. Their debut single "Because I'm a Girl" (Hangul: 여자 이니까; RR: Yeoja Inikka) was a hit in 2001. The music video stars actress Goo Hye-jin, and actor Shin Hyun-joon, which increased initial public interest in the song. The song remained a karaoke staple in Korea for many years.
This helped to launch the career of Kiss, with an album quickly following. However, the group quickly disbanded afterwards, due to internal conflict that could not be resolved.
Umji is now an actress.
"Because I'm a Girl" has been covered by numerous artists, including Korean female duo 2NB.
