"To be honest, Father Yu and Mother Yu don't have the determination to strive anymore.
They expanded the company and worked so hard to make money for two reasons: one was to increase their confidence by having a successful business, and to provide themselves with a good life.
The second reason was for their two daughters.
They did actually make a lot of money, all for the purpose of giving their daughters a better life.
But what about now?
Their younger daughter has run away from home and doesn't acknowledge them anymore.
Their elder daughter is clearly not their biological child; even though she has taken over their daughter's body, in her bones, she is no longer their child. So naturally, they won't show her any mercy, let alone leave anything for her.
Another most important thing is that Father Yu and Mother Yu have realized that Yu Anning is a capable and talented person.
