Being your boyfriend n all, Katsuki was aware of the days when you had your period. He knew generally of when it occurred, so he’d be less aggravated and aggressive around you those days.
And that dreadful time of the month had come a little earlier than expected, 4:00am on a Saturday to be specific. And this lead you to needing sanitary products, and of course other necessities.
So here Katsuki was, driving you down the quiet streets of Musutafu towards the local convenience store. Once you two got there, he came in to make sure there weren’t any weirdos and just silently followed you.
“Get whatever nerd. And make it quick, we need to get back.” He grumbled, handing you his card. He didn’t care how long you took in reality, he just wanted to keep up the tough facade permanently.
