In a recent interview, Krystal, formerly known as Jung Soojung of the K-pop girl group f(x), addressed questions about her late co-member Sulli, sparking mixed reactions from fans.

Krystal, who transitioned from being an idol to a full-fledged actress, sat down for an interview on September 22 in Seoul. The discussion primarily revolved around her upcoming film, "Cobweb," set to release on September 27. However, the conversation took a sensitive turn when a reporter inquired about Sulli's posthumous documentary film, "Dear Jinri," which is slated to premiere at the Busan International Film Festival.

Responding to the question, Krystal admitted she was aware of the documentary but was unaware of its unveiling at the film festival. She further expressed her hesitation to discuss the topic, hinting at the emotional weight it carries for her. Despite her reservations, Krystal showed support for her late friend, stating she would watch the film.

The interview's release stirred various reactions from f(x)'s fandom, MeUs. While some fans were moved by Krystal's mention of Sulli and her use of the term "unnie" (older sister) to refer to her, others expressed their displeasure with the reporter's approach. Fans felt the question was insensitive, considering the close bond Krystal and Sulli shared and the emotional toll Sulli's passing might have had on Krystal. Many took to social media to voice their concerns, urging reporters to be more considerate in the future.

"Persona: Sulli," which includes two short films, is set to release in the latter half of this year. One of the short films, "4: Clean Island," starring Sulli, will be showcased at Leika Cinema on September 27. The documentary "Dear Jinri," capturing Sulli's last interview, will be screened at the 28th Busan International Film Festival on October 4.

The project was initially intended to feature five short films. However, following Sulli's untimely passing in October 2019, the production was left in limbo. The production team eventually decided to move forward with the project to honor Sulli's memory and showcase her talent as an actress.

As the K-pop community anticipates the release of these films, they also await Krystal's "Cobweb," which will hit theaters on the same day as "4: Clean Island."
