Clara wanted to earn a benefit from her husband's side too. He was a commoner but could have her, a very beautiful and talented noble lady, as a wife. He would indeed be regarded as a lucky man for that reason alone, and she would please him with all she had. But of course, in return, he had to please her with all she demanded.
Therefore, she would give all of her to make her dream husband kneel in front of her, being addicted to her and begging for her love and affection. And all of her predictions and calculations were laid right before her eyes, as when they talked in the park. Joanna gave her a hint that she really did not want to continue her marriage, although she wondered why the General came to Terra if there was no affection between them.
But Clara did not want to waste time thinking of that much, as her main purpose was that she did not want to lose the chance to allure the General with all the charm she had.
