The Journey Home Is Treacherous

Dormitory building No. 7, Fourth floor, four-bed room. My bed is already made. The year of admission on the bedside label is last year. … I don't remember enrolling in this university. I don't remember my roommates Zhang Fan and Chen Yu. Can't remember what happened last semester. … But there are three text messages in my phone: A year ago "Trust no one, including yourself." Three months ago "If you see this message, it means you are back." Yesterday's "You left something behind when you were there last time." … Tucked inside the admission instructions was a handwritten piece of paper with a few rules listed on it. The last strip was torn off. My roommate said: You tore it up. Do not you remember? … It's eleven o'clock tonight, on the first floor of the library. The door will open. Last time I went in. … If the person who comes back is really me.
