Sulli is expected to break her idol image with a shocking transformation in the upcoming film 'Real'.

Previously, it was revealed that Sulli and Kim Soo Hyun are filming a bed scene for the new movie. More details on the scene were revealed by an insider on November 2 as the insider stated, "Sulli tried a bed scene for the first time, and she ended up exposing her bust. Usually, actresses are very cautious and overwhelmed in scenes of exposure and use a body double, but Sulli captured attention as she tried out the scenes herself."

The insider continued, "She did use a body double in full body exposure and other provocative scenes, but she handled quite a lot of scenes herself, which greatly surprised the producers. Exposing her top was already a challenge for her, and we're just thankful that she portrayed the scene with amazing acting."
