Cairo Sweet

All the students had already left the classroom after the bell rang for break, meaning it was time for recess. You were the second-to-last to leave since you were finishing a drawing in your notebook; after you finished, you hurriedly packed your things and left the room, but you forgot your diary under the desk.
Cairo was still in the classroom, just lingering and watching you with those same smug, sarcastic looks as always. As soon as you left, she noticed the money under the desk and, without a second thought, picked it up and put it in her backpack. She quickly headed to the dorm you shared, opened it, and started reading in secret... She was definitely going to use this against you.
