Before his rebirth, Jiang Tian was a nerdy academic who didn't listen to what was going on outside the window and did whatever the teacher said.
After graduation, Jiang Tian worked as a teacher for five years and met many "student tyrants" and "school tyrants" of all kinds.
She deeply felt that the life of a "school bully" was much more enjoyable than that of a "student bully"!
After rebirth, Jiang Tian said: I want to be a cool school bully!
