My Happy Marriage by Akumi Agitogi and Rito Kohsaka

The story is set at around the time of the turn of the 20th Century in Japan. After her mother dies and her father remarries, Miyo is considered worthless and is treated as less than a servant by her stepmother and stepsister while her father does nothing to protect her from their abuse.

Part of the reason that she is considered worthless is that she doesn't have a special ability like others in her family do. She has been beaten down by so much abuse that she has given up hope that anything will get better, and that all she has to look forward to is being miserable for the rest of her life.

When she's old enough she's sent off to be the bride of the heir of a noble house. The house's reputation is so bad (the back of the book says that it is "cold and cruel") that all of the previous fiancees could only stand it for three days before leaving.
