After Becoming the Daughter of the Runaway Pregnant Female Lead

The Female Lead Transmigrates into a Book as a CEO Female Villain. The Male Lead Is Her Assistant and an Ordinary Passerby

The female lead transmigrates into a domineering female CEO with a bad temper. At first, she refuses to cooperate with the System's task and says she'll jump off a building. The male lead doesn't have a name at first, just a surname followed by "assistant," and he isn't very prominent. Does anyone know the title? I can't find it anymore.
