No Lights Allowed

On the day when the club's application was rejected, Xu Qingmian discovered an activity room 404 on the fourth floor of the teaching building that should not exist. There is only one rule on the door: ——It is forbidden to turn on the lights. After turning off the lights, students who have been missing for many years will reappear; after turning on the lights, everyone will forget that they ever existed. In order to recover a girl who had been erased from school history, Xu Qingmian was forced to accept one commission after another that no one could remember. She thought she was helping those people leave. Until one day, she saw her name on the yellowed club roster. And the girl Jiang Wantang who was always waiting for her in the dark and called her "president" softly had died in this activity room seven years ago. What's even more terrifying is—— Everyone said that Xu Qingmian was the first person to die.
