On the August 21st episode of SBS‘ ‘Strong Heart‘, Leeteuk said, “I heard about a behind-the-scenes story for ‘To the Beautiful You‘”. He continued, “Mighty Mouth‘s Sangchu made a cameo in the drama and he shot a scene in which he got into a fight with Sulli.”
Leeteuk explained that during one part when Sangchu was supposed to send out a punch with Sulli ducking out of the way, the two missed and Sanchu’s fist ended up making contact with Sulli’s nose. Although Sangchu had tried to loosen the power from his arm when he saw his fist about to make contact with her nose, it wasn’t enough for Sulli’s nose started bleeding from both nostrils.
However, Sulli showed her professionalism and determination to keep going. “It started to bruise up, so I just asked the staff to cover up the bruise and kept continuing on with the shoot,” she said, earning compliments from the guests on the show.
