I'm in love with my wicked wife

Zena was a college student who enjoyed transmigration novels, so she knew all the rules of the game. She also knew that it never happened in real life. But after an accident, she woke up as a despised actress who had just given birth! And unlike her transmigration seniors, she knew nothing about this world she transmigrated to or the woman whose body she inhabited.
After it became increasingly clear to her that she was hated by everyone, but the babies she just delivered, Zena decided to make her own rules based on what she had been reading.
"I have to be the villain in this. It's only logical. I am the villain and that incredibly handsome man, my husband, must be the male lead."
This means in order to survive she has to stay away from him and the female lead, but who is the female lead?

Xerxes Zhen had the perfect life. He was good-looking, intelligent and well-respected -the sole heir to the richest corporation in the country. But after a forced arranged marriage to Xian Mina, his life went off the rails. He despised his wife and after three years, she finally agreed to divorce him. She already signed away their unborn babies. But-
"What do you mean she lost her memories?" Xerxes asked, his brows angled in skepticism.
"She is claiming to be someone else, president. We believe it some sort of delusional disorder." The doctor exclaimed.

Zena simply wants to survive long enough to survive and get the hell out of here. However, how does she survive without any information? What kind of transmigration is this?! Plus, why does she have such unreasonable affection for babies that didn't belong to her?

All she wants to do is stay away from her husband, but she cannot abandon her children for some reason. Plus, someone wants to kill this woman, and she keeps receiving these threatening texts. Is the male lead, not the only one who wants this woman dead? Does she not have any allies? And for goodness' sake, why does he keep looking at her lips like pieces of candied fruit?!

"What are you doing?" Zena whispered as she staggered backwards to put some distance between their bodies.
"What does it look like?" Xerxes replied, his gaze plastered to her lips. Zena swallowed hard and tried to push him away, but his hard body didn't budge an inch. "I'm about to kiss my wife."
My wife?!
"You said you would rather die than touch me."
"Well, I guess I am a dead man then," he said as his head dipped.
