Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Unlike her younger sister, who is called a saint, Feene, who is plain, was treated very badly in her family, the family of the Earl. When she was sent to a dangerous battlefield and was working as an army surgeon, she met the Duke of Leon. If you help him with a healing spell when he is dying, you will be asked to get married later! I suspect that she might be mistaken for her younger sister, but in the Duke's family, she will lead a happy life completely different from her parents'?
