Sulli attempted a complicated action scene involving wires and being in the air. 

On the new SBS drama "To the Beautiful You," which will air on August 15, Sulli plays Koo Jae Hee who infiltrates a male sports high school by cross-dressing. It's expected that the drama will portray the episodes surrounding her disguise and her potential romance with Minho.

People are now paying attention to set stills of Sulli attempting wire action. On a carry-on luggage bag attached to wires, she put herself in it in order to portray sliding down about 10 meters down the stairs. Sulli was able to carry out the scene with a slide wire and an aerial wire action and audiences are eagerly waiting to see the result of such a complicated scene. 

There are also stills of Minho and Sulli scrutinizing a pair of teddy bear underwear. Minho is confused as to why Sulli is wearing such things, and while trying to hide her true gender, she's proudly waving it in front of him. The episode surrounding this teddy bear panties is garnering more curiosity. 

The carrier wire action was filmed on July 29 at a university in Icheon in Kyungkido. Sulli didn't use a stunt person in order to portray it realistically. Though she was scared and nervous at first, she went ahead with it, getting applause from the rest of the cast and crew on set. 

While Sulli was attempting such a difficult scene, Minho was by her side to make jokes and make sure that she was feeling comfortable. It seemed to put her at ease and she was able to really express what she was going through. The two leads seemed to be getting close as the shooting went on.

The wire action scene that Sulli filmed will be featured in the series premiere set to air on the 15th.
