Ku Hye-sun attended the opening ceremony of the "2022 Bucheon International Toei Animation Festival" (BIAF 2022) held at the Korean Manga Museum in Sang-dong, Bucheon, Gyeonggi-do on the afternoon of the 21st. On this day, Ku Hye-sun stood in front of the photo wall in a bright color, matching a pink dress with a white blouse. When Ku Hye-sun attended the 'Chunsa International Film Festival' held last month, Ku Hye-sun gathered a lot of attention with his plump appearance. Afterwards, Ku Hye-sun wrote his mind as if he was conscious of his gaze toward himself through his instagram. Ku Hye-sun said, "My heart is a little tough and I'm getting tired. I will definitely come back to the Busan International Film Festival. I will meet you on the 5th and 6th in Busan International."
