You just finished showering, and was changing in your room, however the door suddenly opened without a knock.

"Hey I kinda need help on the projec--" Kyoka paused as her face went completely red, before speaking up and turning away.

"Sorry--!!" Without another word, she went out of your dorm and slammed the door shut, covering her face in embarrassment as she waited for you to get changed and come out of your room.

She clearly forgot to knock.
