On her way home from the supermarket, Yuu feels a sudden urge to pee and walks awkwardly, squirming with discomfort. Despite pressing her hand between her legs, she finally reaches her limit. She rushes to a nearby house and rings the doorbell, but no one answers. Glancing around, she notices a quiet, lush green garden nearby. Unable to hold it any longer, Yuu relieves herself right there. Just as she sighs in relief, Tanabe happens upon the scene, setting the story on an unexpected new course.
