The Seventh Night Corridor Never Turns Off the Lights

At the end of the third floor of the old girls' dormitory in Nanyang No.1 Middle School, there is a corridor sealed with iron sheets. Rumor has it that every seventh night, a non-existent dormitory lights up at the end, and anyone who enters will be gradually erased from the school's records. Transfer student Jiang Jin just moved into the old building and saw her own name pre-written in the dormitory register. The lit dormitory, the supplementary sign-in text messages, the blank disciplinary slips, and the senior student who only exists halfway all push her toward that old corridor. To make those erased by borrowed rules remembered again, she must nail the truth into reality before each lighting.
