On the special broadcast 'Exomentary Stage Main Cam', EXO's Chen revealed a behind story about Baekhyun, Lay, and underwear!

Chen said, "It was at our dormitory. Lay hyung took a shower, but he didn't have any underwear to change into. So Baekhyun gave him brand new ones that were unopened in its original pack."

Lay then added, "Baekhyun was originally trying to give me his underwear that he had worn before." To this statement Baekhyun strongly disagreed, and shouted, "How can I give someone the ones that I wore before?"
