Dear Mine

Satoko is a domestic girl with a kind heart. She lost her father when she was little, and her family has been very poor ever since her father's company shut down. However, life is happy enough when you are optimistic, and Satoko enjoys her daily life heartily. One day, she is rescued from a attacking dog by Fuuma, an extraordinarily mature 10-year-old boy. Little does Satoko realize that this boy is the head of Wakudera Corporation, as well as her future husband!
