Because love has a miracle, why did Wu Meizi become the heir?

Wu Meizi is Lin Tianyou's second wife. His first wife, Yuan Angel, was looked down upon by her mother-in-law because of her poor family. In addition, Lin Xiuqin's ex-husband cheated on her baby-sitter, which made Lin Xiuqin very disgusted at the sight of young, beautiful and smart women. She thinks such a woman is a fox who will seduce a man. So she tried every means to break up Angel Yuan and her son. But what goes around comes around. Although her second daughter-in-law, Wu Meizi, is a rich woman, she is not so easy to bully. It can be said that she bullied Lin Xiuqin in turn.

The second marriage between Lin Tianyou and Wu Meizi didn't end well either. Because Wu Meizi's provocation is not good for her mother-in-law, not only Lin Xiuqin can't stand it, but even Lin Tianyou can't stand it. In addition, I have been thinking about Angel Yuan, so this marriage ended hastily. However, at the time of divorce, Wu Meizi took the opportunity to knock on a lot of Lin's property and played some means to make Lin's family almost bankrupt.
