On March 25, Ryu Gyeong Su sat down for an interview with news outlet 10 Asia.
Ryu Gyeong Su said, "I made a very brief appearance in 'Midnight Runners' (2017) and 'The Divine Fury' (2019), which are both Seo Jun's films."
He continued, "I didn't think that he would recognize me when we met for 'The Divine Fury', but he remembered me. I was surprised and touched."
He added, "While filming 'Itaewon Class', Seo Jun and I became a lot closer. Seo Jun has such an incredible personality. He always made the whole team smile and laugh."
