A group of four girls in school uniforms stand together, smiling and posing with their arms outstretched in a classroom setting. The scene cuts to a boy lying on his stomach, blushing and smiling with his eyes closed, followed by a girl in a school uniform standing in a dark room with a bright light source behind her. The sequence ends with the girls peeking from behind a door, looking surprised as they face a boy with blue hair.
