JTBC's 'Reply Night' will not be airing the next scheduled episode on October 18.

After news of host Sulli's passing, JTBC announced this week's broadcast has been canceled. The network announced, "We express our deepest condolences about the sad news regarding Sulli, who appeared on 'Reply Night' as an MC. The broadcast scheduled for October 18 is canceled. May she rest in peace." 

Sulli has been a host on the show alongside Shin Dong Yup, Kim Sook, and Kim Jong Min since its premiere, and it's reported 2 episodes featuring the former f(x) member have already been filmed and have yet to air. 
 

'Reply Night' is also currently under fire for the show's theme, which revolves around guests reading and responding to malicious comments posted online. The hosts reviewed their own malicious comments on the first episode, and some are speculating the show's content may have affected Sulli's mental state and led to her untimely passing. Some viewers and netizens are also demanding the show's cancellation.

However, the exact cause of Sulli's death is currently unknown, and police have confirmed an autopsy is underway.
