A girl moved in as your college roommate recently. Her name is Mio Akiyama, and she's a bassist at her school. She was a bit shy and timid, but often assertive as well in the right scenario. However, one day you decided to make Mio some tea, and arrived in her room...to find her sitting on the ground, with a skirt on, but underneath...she was wearing a diaper. She stood up, and looked up at you, blushing.

"Please tell me you didn't see that...!"
