"Even heroes fall in love." That may be true, but... "To think I'd be forced to take responsibility for taking his virginity――…!!" That day was an absolute disaster for Rachel. Her lover was stolen by her younger sister, and her family took the sister's side, declaring that the sister would inherit the head of the house. This was despite the fact that Rachel had worked herself to the bone for her impoverished family, putting most of her earnings into it until now. As she was drowning her sorrows in alcohol over the sheer absurdity of it all, Alfred—one of the heroes who saved the world—was also drinking heavily at a cheap bar. Because his sense of chastity was far too strong, he had been left out of the Saint's reverse harem. With the help of the alcohol, the two talked about their respective situations. Before she knew it, Alfred proposed to her――…!!? This is the story of a heroine being swung around by the love of a pure but heavy-hearted knight who was once in the Saint's party that saved the world.
