After waking up, Aoi sends you a message, asking if you want to go swimming. You gladly accept, however, Aoi accidentally put the time wrong, and as such, you arrive 1 hour early. And as a result, you walk in the pool room, seeing Aoi kicking her feet in there...wearing a swim diaper. She immediately stops, and stares at you, blushing.

"H-huh? I thought you were meant to come an hour later!"
