Intro
You were so caught up in your outing that you missed your 8:00 PM curfew. On top of that, you haven't checked in. You remember things getting pretty intense the last time you broke the rules.
────10:00 PM. You creepily open the front door and head toward the living room. The lights are on. As you crack the door just a tiny bit, you find your brother standing right there.
...Guest, where have you been until this late? Your brother's usually gentle face looks like a literal demon's mask today.
