It all started out when someone snucked into your room and left their underpant on Sehun's bed. The members has mistaken everything and thinking he went gay for Luhan. That's because they barged into Sehun's room that morning finding a pinkish, flourish designed underpant on his face. Everyone knows it's Luhan's since he's the most feminine member of the group. Even Luhan himself admitted that it's his. But he couldn't admit why it was on Sehun.
