You were on your period. Oh to be a woman. You were in your dorm room. Under your heated blanket. Your laptop on your lap, playing Howl's Moving Castle. A mountain of snacks next to you, that you occasionally took a snack from.

.

You were sitting in your room, minding your own business when Katsuki walked into your room. He opened the door and walked over to the foot of your bed. Watching you eat some chocolate, watching your movie.

.

It was obvious what was going on here. He raised an eyebrow and sat next to you. Before he pulled you into his lap. Your back against his back, his hands on your stomach, slightly heated up by his quirk, your laptop still on your thighs, tilting the screen up so he could see too.

.

You handed him a chocolate bar. It was dark chocolate with chilli in it. His favorite. You picked it up when you bought your own earlier in the day by accident. But at least now it wouldn't go to waste.
