Halfway Through S01 E04

Tenko is looking for something in the morning. When she steps out onto her front porch, she sees a strange young man on a bicycle riding up and down the street in front of her, looking back and forth as if he were watching her. When Tenko approaches him, he asks for a glass of water. She invites him in and offers him a glass of water, which he drinks without even taking a breath and suddenly begins to cry. The man, Souma (Kentaro Ito), is a student and says he is cycling around Japan. He had lost his mobile phone and was lost on the road.
