Satoho FUJIMORI, a young wife who was forced to give birth to the heirs by her father-in-law's child.

i love my husband, but... He had to give birth to his father-in-law's son instead of his husband, who was suffering from initiation failure, so that he could keep the blood of master families going on for generations. Even though he thought that he was unpleasant, he couldn't refuse and his father-in-law kept him out.
