Kelly (BADVILLAIN): Profile of BPM Entertainment’s Rising Maknae Vocalist

Kelly is the maknae and vocalist of the seven-member South Korean girl group BADVILLAIN, a 5th generation K-pop act formed by BPM Entertainment — the same label behind VIVIZ and home to labelmates like Taemin and BE’O. Born Ha Seo-yeon (하서연) on June 16, 2006, Kelly was the very first member unveiled for BADVILLAIN, introduced to fans on May 16, 2024, ahead of the group’s official debut with the single album “Overstep” on June 3, 2024.

Before joining BPM Entertainment, Kelly built her foundation in dance and performance through STAGE631, a well-known dance academy run by choreographer Bae Yoon-jung, and she also trained at Def Dance Skool. Her educational background includes Duksung Girls’ Middle School and Seoul Broadcasting High School, where she focused on broadcasting and entertainment performance — training that helped shape her stage presence as a K-pop idol today.

Role in BADVILLAIN

As the group’s maknae, Kelly brings a youthful energy that balances BADVILLAIN’s bold, girl-crush concept. She contributes as one of the group’s vocalists, supporting title tracks like “Badvillain,” “Hurricane,” “Zoom,” and “Thriller.” Fans and fellow members alike describe her as “weird, but mature,” a personality trait that has made her a fan favorite within the fandom, officially named VILLAIN-ON.

Personal Facts

Kelly stands at 165 cm (5’5″) tall, holds an ISTP MBTI personality type, and was born under the Gemini zodiac sign. She comes from a family of five, including an older sister and a younger brother. Her nickname, “Goneugi,” given to her by member YunSeo, playfully combines the Korean words for kitten and baby wolf. Kelly has also shared that her cat is her most treasured possession, and that purple is her favorite color.

Career Highlights

Since her debut, Kelly has promoted extensively with BADVILLAIN, whose lead single “Badvillain” reportedly surpassed 10 million YouTube views within just 17 hours — the fastest debut record for a 2024 girl group. As BADVILLAIN continues to grow its discography and expand its fandom internationally, Kelly remains an essential part of the group’s vocal line and youthful identity on stage.
