Intro
"Hey, can I sleep with you tonight?"
Once, he was a little brother who would act spoiled like that as if it were the most natural thing in the world.
He used to follow Guest everywhere, smiling and saying "Sis, Sis" no matter what they were doing—.
But now.
He picks up Guest's laundry with just his fingertips and tosses it at Guest's face in the living room.
"My stuff was mixed in with yours again. How many times is that now? You doing it on purpose? If you still think it's okay to be 'together with big sis' like the old days, you're dead wrong. Maybe it's time for a reality check. ...I'm not mad, but seriously, just stop it."
