According to Korean media reports on April 11, an interview from SBS's "Access Showbiz Tonight" in 2017 attracted attention again.
Interview with members of the cast of the movie "Real" Kim Soo Hyun, Sulli and Jo Woo Jin. At that time, the film attracted attention for having Sulli's first nudespace.
In that interview, when the reporter asked: "Will you sleep well last night?" Sulli replied, " Yes, I slept well." Kim Soo Hyun then added, "It seems like you're the one worried the most."
When the reporter asked for a brief introduction to the film, Kim Soo Hyun replied, "In short, it's like a gift set." He continued to share: "It took me more than three hours to read the script for the first time. After that, the script did not let me sleep. At first, I thought I would take on and complete it, but after filming 101 scenes, I became more modest."
Jo Woo Jin also commented, "You can really feel on set that Kim Soo Hyun is completely immersed in this film. This film is "of Kim Soo Hyun, because of Kim Soo Hyun, because of Kim Soo Hyun".
When he heard this from his colleague, Kim Soo Hyun was surprised and said, " Sunbae-nim (the way to talk to an older person - PV), if he spoke in the same voice, it would be scary".
After that, Jo Woo Jin added that his most memorable character in the film was "Song Yoo Hwa", played by Choi Jin Ri (Sulli), praising her acting despite her relatively small role compared to the main role.
Recently, on March 28, 2025, Sulli's family issued an official statement asking Kim Soo Hyun and the film's director Lee Sa Rang to explain some concerns: "Why was Kim Soo Hyun's sleeper not stated clearly in the script; why was Sulli accused of filming the nudes and sleeper scenes despite the presence of a stunt double on set; why did the film crew mistakenly claim that Sulli was absent due to illness when she had scheduled to film those scenes."
Sulli passed away on October 14, 2019, at the age of 25. Throughout her life, she has endured many controversies and bullying online. In July 2014, when her relationship with Choiza of Dynamic Duo was made public, she was harassed and rumored fiercely online, forcing her to temporarily stop working in the industry and eventually leave the group f(x) in 2015.
