It is late 1921, the 10th year of the Taishō era. Tamahiko Shima, second son of the wealthy Shima family, has his life turned upside-down after his right arm is paralyzed in a car accident that also claims the life of his mother. Now seen as worthless to his calculating father’s long-term plans for his business empire, his family treats him as “dead”. But since it would bring shame to the family were they to disown him outright, he instead finds himself shunted off to a villa in the mountains of Chiba, out of public view. Though he quickly resigns himself to the idea that he will die alone and forgotten, one snowy December night a girl appears at his doorstep and announces that she is there to be his live-in caretaker, and when she is old enough, his bride. The girl, named Yuzuki Tachibana, or “Yuzu” for short, was purchased from her impoverished home by Tamahiko’s father, and while she too finds herself uprooted from her home and family, she throws herself into her new role with gusto.
