Many are questioning Bang Si-hyuk's relationship with a 2000-born influencer, Se Yeon, and her older sister, whom he was seen with in Los Angeles, the United States. On August 8, the popular YouTube channel "I am WalKing," with 170,000 subscribers, posted a video titled "Best Highlights of July 2024." In it, Bang Si-hyuk is seen crossing a street in Beverly Hills with two women—one identified as AfreecaTV BJ Se Yeon, a well-known internet personality born in 2000, and the other her older sister.

They were captured by a camera operated by someone who was not Korean, completely by coincidence. Se Yeon had previously shared photos of her LA trip on Instagram on July 29, confirming her presence in the video. Following the video's release though, Se Yeon disabled comments on all her social media accounts.

With speculation about their relationship intensifying, HYBE Labels released an official statement on August 9. They clarified, "Chairman Bang Si-hyuk recently ran into Se Yeon's older sister at a gathering and gave advice on handling different situations in the entertainment industry. When the sisters later visited LA and asked for recommendations on tourist spots and restaurants, he helped with reservations and provided guidance.

" However, shortly after this statement, another photo surfaced showing Bang Si-hyuk taking pictures for Se Yeon's older sister on a street in LA. This image suggested they were spending more time together in LA than just arranging reservations, furth.
