My classmate Sayoko Miyamura is an honor student, friendly and popular. She is a girl like Takamine's flower that Eto secretly has feelings for. When she was wandering around at night, she saw Sayoko Miyamura, who was having trouble with some men. Eto tried to pretend to be indifferent to her and ignore her, but she decided against him and intervened. The two hold hands and run away from the place. It's somehow different from the impression I see at school during the day. Sayoko Miyamura, not Sayoko Miyamura...she had a dual personality. Her personality is ``Yako'', created in order for Sayoko to be a good girl. She appears at night and has a completely opposite personality. She was rebellious, foul-mouthed, and sexually active.
