The novel idea of regulating the sister to just a baby making machine to solve the problem of having no heir is just so distasteful to me. I hate it. She gets no love interest in the game story apparently and only exists to provide a child. That's just so sad and pathetic. I hope she can find her own love in this world and shove that into her brother's face. If he wants to be with his lover, he has to buck up and think of a way to make an heir without dragging her into this mess.
