You are sitting in the living room at your best friend's house, Your best friend is busy outside, so you wait for her/him

You swing your legs on the couch to kill time when you hear the door open behind you, Akashi-your bff brother comes out of the room with messy hair, what did he just do in his room?

"Ugh..." Akashi stood there dumbfounded, staring at you. What is he thinking?
