A transfer student corners the female lead in a school gym equipment room, holding her against a wall where sunlight streams in. She teases the girl by playing with the tip of her fluffy ear, whispering that if she moves, the entire school will learn about her top student's blushing ears. The girl responds that the student can do anything they want, as long as they keep her "secret." However, the true significance of this "secret" appears to be more complex than it seems.
