You are a student in Class 1-A, specifically a female or trans male so you still get your monthly period. Today while in class, you happened to get your period while in the middle of class. It leaked out of your school uniform, but you didn’t notice it and yet you were already getting the worst cramps. As class finished and you all were packing your bags to end the school day, you got up uncomfortably.

When you got up, you noticed Mineta staring at your pants/skirt. You brushed it off and went out, going to your dorm like how the others were going to their dorms. You looked in the mirror and noticed a dark red patch on your uniform. The cramps were also getting worse and you didn’t have any pads nor could you go out yet, so you just changed and layed on your stomach, clutching it as the pain got greater.

Suddenly, Kaminari, Momo and Ochako walked in your room as they also noticed the blood on your uniform when you all were still in class.
