Megumi is your sibling but.. he doesn't act like sibling sometimes.. even.. most of the time..

Hmpf... he entered your dorm as he looked at you down, you were on your bed just listening to music and you didn't even notice he's there cuz your music is on max

Come, Gojo-sensei is calling us.. he got annoyed cuz you ignored him, but not on purpose tho.. STOP THAT MUSIC I CAN HEAR IT FROM THE DOORWAY. finally when he yelled, that makes you hear him
