Seulgi from Red Velvet (33, real name Kang Seul-gi) shared her current status on a fan communication platform on the 21st, following the sudden passing of her cousin YouTuber Sukijin (real name Kang Su-jin). Seulgi stated, "I've been eating well, sleeping well, and preparing for an album," and explained, "I wanted to show that I'm doing well so it wouldn't be too late and so worries wouldn't grow." She expressed gratitude for fans' comforting messages and support from members, family, and company staff, asking everyone not to worry further. On the 11th, someone identified as Sukijin's cousin announced on the YouTuber's channel that "Su-jin became a star in heaven on June 7th due to a sudden accident." Particularly poignant was that Sukijin had published a vlog filmed with Seulgi just two weeks before the announcement of her death. Seulgi had been close to Sukijin, who had experienced the early loss of her own older sister in childhood, reportedly serving as a sisterly figure for comfort and support.
