I found a bag, took photos of what was inside, and posted a lost-and-found notice in the school group chat
[Who here is Zhong Bai? I found your student ID and a purple electronic device. If you see this, please add me so you can claim them.]
That night, the school group chat exploded.
[Holy crap! The school bully!]
[Holy crap! The school bully and a purple mood!?]
[That thing belongs to the school bully? You'd never guess! The school bully is the bottom!]
A few minutes later, I had a friend request and three “friendly” [?] messages.
