Female college student Hua ( voiced by Aoi Miyazaki ) and him ( voiced by Osawa Takao ) soon fell in love. Hua later learned that he was a werewolf living as a human, but Hua's heart for him remained unchanged. The two began to live together, and later they gave birth to two new lives. The older sister who was born on a snowy day was named Xue, and the younger brother who was born on a rainy day was named Yu.
Xue is lively and curious, while Yu is sickly and timid. Their family seems ordinary, but the two children are the children of wolves who possess the two traits of humans and wolves. In order to conceal this fact, a family of four lives quietly in a corner of the city. Life is plain but happy. I thought that such a happy time would last forever, but because of the sudden death of the werewolf who was the head of the family, he was abruptly deprived.
Although Hua suffered from the loss of her husband, she still vowed in her heart to raise her two children properly. In order to allow her children to freely choose to be humans or wolves in the future, she resolutely decided to avoid urban people and move to a country where the environment is harsh but rich in nature.
