Sports Seoul reported that in the post on February 2 by Sulli's brother (called A), the four characters Kim Soo Hyun, Lee Sa Rang (real film director), Lee Jin Ho (YouTuber sued by Kim Sae Ron's family) and Kwak Tae Young (former manager of Kim Sae Ron) were expressed as "the center". The original director of the film Real Lee Jung Sub and actress Han Ji Eun (a supporting role in Real) were commented as victims.
Sulli's brother also emphasized that "IU is close to Kim Soo Hyun" and revealed that she "rejected the initial female lead role in Real, then gave the script to Sulli".
According to A, all three people Sulli, Goo Hara and Kim Sae Ron were trained as psychologists at the same hospital, and that hospital was initially introduced by IU to Sulli.
Sulli's brother also mentioned many other artists including Suzy, Ahn So Hee and made speculative revelations without any evidence.
After listing the names of many artists, A continued to raise doubts about Sulli's nativity scene when he said: "It was done according to the script, but if they intended to edit it to this extent after the release, then why use a stunt double?"
According to A, Sulli's former manager confirmed that the stunt double was present at the studio. A added: At that time, Sulli was having physical and mental difficulties, and he was very stressed during filming.

Sulli's brother's post was met with backlash. Many netizens criticized him for mentioning a series of celebrities in a messy manner and making speculative revelations.
When a netizen commented: "This time, he grabbed IU's hair. I really hope IU will sue him," Mr. A expressed his confidence in the answer: "I will sue her. I have enough witnesses to witness."
After A's post, Kim Soo Hyun's side officially denied the accusation of forcing Sulli to act in a hot scene.
Kim Soo Hyun's management company, Gold Medalist, stated, "Actress Choi Jin Ri (Sulli's real name) was well aware of the sleeper scene before filming it.
When writing the contract, the film crew included a separate clause about her body exposure level. The actress and management company SM Entertainment carefully reviewed all the content before deciding to appear in the film.
To prove this claim, Kim Soo Hyun's side has published a field inspection report from the assistant director and screenwriter of the film "Real", as well as a part of the book of scenery tablets detailing the hot scenes that the actor had to perform.
According to assistant director Kim Joong Ok, there are no stunt- performers on set, only stunt actors. This person does not replace the main actor in hot or dangerous scenes, but only plays the role of imitating the actor's movements during the filming preparation stage.
SM Entertainment managers were always present on set. If there is a problem with the sleeper or the stunt scene that the actor is forced to do, it is an issue that Sulli's management company cannot ignore.
After Gold Medalist's statement, Sulli's brother deleted the above post. But he responded to Star News on September 3: If there was really no problem during filming, please be transparent about why director Lee Jung Sub left the mid-term position.
As far as I know, when he was still in the role of director, he had completed 80% of the filming progress. The fact that most of the films have been filmed and are still replaced is something I cannot understand. If there is any point in what I say that is wrong, please point it out clearly.
