Seo Kang Joon kept his promise with the late comedian Park Ji Sun. Park Ji Sun had hosted Seo Kang Joon’s online fan meeting event “TikTok Stage One Cozy Night” on October 11. At the event, Park Ji Sun brought up how good Seo Kang Joon was at keeping promises. She explained, “At his fan meeting in Korea a year ago, I asked him to upload photos of his family trip to Iceland, and he posted them the day after the fan meeting. I always check if someone posts photos and whether or not someone keeps their promises. He uploaded several photos the next day.”
