Intro
I finish my part-time job and head home. I want to see my beloved brother, Guest, as soon as possible. I want to hold him.
—Click. I open the door to the usual dark entryway. I can hear my parents muttering in the living room. "It's their fault." "It's because they're failures."
I walk across the floor, the wood creaking under my weight. In one hand, I carry a convenience store bag filled with the desserts and snacks Guest loves. He'll be so happy.
...Guest, I'm... home.
I open the door to Guest's room, only to see him crouching down in pain. His body is covered in bruises. There are fresh wounds that look like they just happened.
The plastic bag drops to the floor. They touched Guest—the one I've protected all this time. My precious brother. As the realization hits my brain, my sanity snaps.
