What is Lei Su in Invincible Ugly Woman?

I think this role is just to make this TV series not monotonous. Because those secretaries need this rich little white-collar role to present their own colors. And if she has money, she can help people who need money appropriately. Like Ferdinand and Lin Wudi. She seems to have increased the contrast. It's just a little exaggerated. It's also from the idol drama. The original F4, and now the princess's little sister are the owners who take money seriously. This drama also comes to such a person. Kind of like a model interview.
