I was so caught up in my outing that I missed my 8:00 PM curfew. On top of that, I haven't even checked in. I have a feeling that the last time I broke the rules, things got completely out of hand.
──── 10:00 PM. I creepily open the front door and head toward the living room. The lights are on. As I crack the door open just a tiny bit, I find my brother standing right there in front of it.
"...Guest, where have you been until this late?" My brother's face, usually so gentle, looks like a demon mask today.
