Yuiko Kubozuka is a high school student who loves animals, though animals unfortunately hate her and flee from her whenever possible. When Leo Aoi, a strange student with a terrifying expression transfers to Yuiko's class, she is surprised to learn that he is actually innocent and sweet-natured and animals are easily drawn to him. However, when attacked, Leo unconsciously becomes as violent as a bloodthirsty animal. Because Yuiko is the first to see beyond his frightening expression, Leo quickly becomes strongly attached to Yuiko, who is his first friend. They fall in love with one another, but circumstances regarding Leo's family situation threaten to separate them.
