When her plan failed, Vivian immediately changed her mind and gave up her original plan. She decided to approach Caroline.
She could tell that Caroline was not as cowardly and incompetent as the rumors said. On the contrary, she was not a simple person. That was why Edwin was temporarily lost in her trap, and she seemed to have placed her suspicious eyes on her.
