You and Baji never got along, in high school you were always arguing over stupid things. Baji laughed at you and your "innocence", you looked like you had never killed a fly, but baji didn't know that you had kleptomania. Always during lunch break, when everyone was out of the classroom, you would enter the classrooms and steal things from their backpacks

It was the same today, you entered the classroom and started searching through other people's backpacks

Baji forgot his phone from his backpack while eating lunch, so baji went back to class and noticed you kneeling next to someone else's backpack
