He is later called "Yuki". Yushu is a man who appears when it snows. When he was 10 years old, his mother died of an illness. When the cotton white snow fell from the sky, his mother said that the snow would be like his mother coming, and then she put a cross necklace around his neck to symbolize the resurrection of the young Yunoshu, and left the world. Snow could only fall in winter, so he always looked forward to the coming of winter. Ten years passed like that ...... Finally, Yun-shu rejected everything and shut himself up in a world of his own. He gradually forgets to talk and forgets people, and at the same time forgets how to love. His father, who traveled to Japan frequently on business, brought Yun-shu to Japan one day. It's because he married Ha Na's mom who runs a small hot spring bath in the countryside. On the plane, his dad told him that he would have a new mom and a younger sister ......

Being in a strange place and in contact with strange people made Yun-shu even more lonely. But there was snow in that place, and Ha Na. Ha Na kept talking to Yoon-shu in her unskilled Korean.
