As we know, Sehun and Chanyeol have just made a comeback as the EXO-SC sub-unit. They also did various promotions, including appearing on the Youtube program, Piki Pictures. Here, they were asked to speak as softly as possible without waking up the 'mothers' sleeping behind them. If their mother woke up, they would be punished by wearing various strange accessories.
In the teaser video of this event with EXO-SC, Sehun is seen wearing a blonde wig, headband, women's clothes, and glasses. Screenshots of Sehun with that appearance went viral among fans and even became edits for memes.
