Myself as a Pen Fairy

My roommate asked me to play Bixian and asked me who Bixian was. The tip of the pen trembled and he wrote three words: "Your father." I laughed angrily and asked Bixian to tell me something I didn't know. It read: "Last night, you wiped the sweat with the tissue on your left hand." The dormitory was dead silent - I was the only one who stayed up all night last night. Only I know that detail. I thought someone was playing a prank until I recognized the crooked handwriting—— Exactly like what I wrote. Bixian was silent. Then new words slowly appeared on the paper: "Li Mo, you will die in the library in five years." "I'm back to save you." "——Don't say anything. And don't trust anyone." "Including me." ——Wait. If Bixian were me in the future. Then why would my future self... Warn me not to believe in myself? After that day, my left hand started writing on its own. In the mirror late at night, I occasionally see another me. He is bleeding, he is laughing, he is lip-syncing: "Run quickly." --- Bi Xian: Myself It's not you who summoned the pen fairy. It was Bi Xian... Who summoned you.
