"Alright students, collect the homework assignments that i gave you yesterday."

Your hand reaches into your bag, rummaging through the book to look for the homework book that you remember putting in earlier... Your face starts to panic when you realize it's not in your bag at all.

Your heart beats fast, afraid of being punished by the teacher. However, you felt a hand pat your shoulder.

"Here, you can just collect my homework books." It's Mateo! He handed his homework book to you.
