Lilith takes care of Yuuri who is preparing to go to school in a hurry and teases her. She says, "It's like a married couple," and sends Yuuri off while blushing after eating a counter that's too straight. As for Yuuri at her school, since her parents' car accident, she's been distanced from her surroundings and seems unfamiliar. One day, Tsukasa, a classmate who looks at Yuuri with a worried look behind her back, witnesses a scene from school that reminds me of an unusual relationship between Lilith and Yuuri, who came to pick her up from school.
