Belle

Who Is Belle?

Belle (Anabelle Shim (Shim Hye-won)) is the main vocalist of the K-pop girl group Kiss of Life, one of the most talked-about 4th and 5th generation K-pop groups to debut under S2 Entertainment. If you’re a KISSY — that’s the group’s official fandom name — or you’re just getting curious about this rising K-pop girl group, you’re in the right place to learn everything about Belle’s story, from her pre-debut trainee days to her role in hits like “Midas Touch” and “Sticky.”

Belle’s story is a little different from most rookie idols — she was already a working songwriter before she ever stepped on stage as a performer. Born Anabelle Shim (Shim Hye-won) on March 20, 2004, in Seattle, Washington, Belle is the daughter of veteran Korean singer Shim Shin, so music was always part of her life.

Before debuting with Kiss of Life, Belle co-wrote LE SSERAFIM’s “Unforgiven” and composed (G)I-DLE Miyeon’s “Softly” and “Charging.” She even sang background vocals on NCT member Mark’s solo track “Child.” That’s a serious résumé for someone who hadn’t even debuted yet, don’t you think?

As Kiss of Life’s main vocalist, Belle now brings that same songwriting sensitivity to her own performances, anchoring vocal lines on hits like “Midas Touch” and “Bad News.” Her rich tone and emotional delivery — inspired by artists like Ariana Grande and Sabrina Carpenter — have made her a standout voice in one of K-pop’s most acclaimed rookie discographies.

Why Fans Love Belle

Let’s be honest — it’s easy to see why Belle has become a fan favorite. She brings a mix of talent, charisma, and relatability that keeps KISSY coming back for more. Whether you first found her through a viral stage clip or a heartfelt fan-meeting moment, you’ll quickly notice why she stands out even in a group as dynamic as Kiss of Life. So next time you stream a Kiss of Life title track, take a moment to watch for Belle’s parts — you might just find a new bias.
