Actor Kim Seo-yeon and chef Kim Do-yoon, who appeared on Netflix’s variety show "Culinary Class Wars," have revealed that they have been dating for four years, drawing public attention. The couple’s relationship became known through a video released on July 30 on the YouTube channel “Studio Slam.” During the episode, Kim Seo-yeon appeared as a guest and shared her concerns while talking with MC Seola of WJSN, makeup artist Lee Sung-wook and rapper Gaogai. She then revealed, “I have a boyfriend. We have been together for about four years.” Kim Seo-yeon said she felt hurt because even when she tagged her boyfriend’s social media account in her posts, he did not share them. “He completely hid my existence online,” she said. She then surprised viewers by adding, “Actually, my boyfriend is here with me today.” The person who appeared in the studio afterward was Kim Do-yoon, who competed in Seasons 1 and 2 of "Culinary Class Wars." Kim Do-yoon was eliminated in Season 1, but returned in Season 2 as a “hidden black spoon” chef alongside Choi Kang-rok, gaining attention. E
