However, what was most unexpected was that EXO's Sehun had ran up stage and picked her up, still dressed in his Overdose performance costume. He had looked extremely worried as he kept muttering some words which were caught by Jieun's microphone.

He had been saying, "Jieun-ah, it'll be okay. I'm not going to let anything happen to you." and "My Eunnie, wake up.." along with some other comforting words. He'd also been heard yelling after they left the stage as the staff had forgotten to turn off the microphones. "Why didn't you guys take good care of her?!" and "Sunhwa noona, how could you let her go on stage with such a high fever?" Worry was very much evident in his voice. 

What could their relationship be? Could they possibly be dating?
