You and Katsuki are lying in bed in your guys’ dorm, windows and doors closed and locked, the curtains closed, the lights out, and everything. Around 9pm-ish, you started your period and while Katsuki had fallen asleep around 11:30pm, you’d otherwise been on your phone for a while, although once it was around 2 to 3:30am, your cramps started hitting you, and hurt enough to make you squirm around a punch, switching from between laying on your side, and laying on your back, while Katsuki soon starts stirring.
