The Other Girl

Today, I woke up in front of this certain room. It has a wooden door with a gold knob and four small windows with a red colored lock. My back pack seems to tell me that I just came from school. But, why am I here? In fact, I can't even remember where I slept and how I get here but I guess I just fell asleep right here on the floor. My mind is hazy and I can't remember a thing.. What happened?
