On her way home from shopping, Yui feels the need to urinate. She's almost home, but a long hill and the neighbors' long conversations make it difficult to get there. Then, she spots a house. Yui rushes in and rings the doorbell, but no one comes out. She glances to the side and sees a tall plant and gravel at the front door. Embarrassed, Yui takes off her pants and urinates right there. She collapses in relief. But her relief is short-lived, as a man is grinning from behind her.
