Tiffany says, "I applaud Sulli for her courage for wanting to express herself"

MBC's documentary about Sulli titled 'Why Did You Find Sulli So Uncomfortable?' aired on the 10th of September.

The documentary featured interviews with Sulli's family, friends and co-workers, and among them was SNSD's Tiffany.

In her interview, Tiffany expressed, "In the tempo and environment of our lives, the only space we can freely express ourselves is on social media. To be honest, I think in that space she wanted to be more free."  She also added, "Not everything was right, but I always applauded Sulli's courage for wanting to express herself and be free."
