Shim Hye Won, better known by her stage name Belle, is a Korean-American singer, songwriter, and member of KISS OF LIFE. Born on March 20, 2004, in Seattle, Washington, Belle grew up in a family deeply connected to music. She is the daughter of legendary Korean singer Shim Shin, whose successful career in the 1990s exposed her to the entertainment industry from a young age. Long before becoming an idol herself, Belle frequently appeared on television alongside her father and developed a natural comfort in front of cameras.

She contributed to songs for LE SSERAFIM, Miyeon of (G)I-DLE, PURPLE KISS, and other artists, building one of the most impressive pre-debut résumés among fourth- and fifth-generation idols.
