He is high above, the mysterious and terrible King of the Wild. With one glance, he can see people’s romances. He hates women to the extreme, but at his first glance of her, he dotes on her and spoils her.
She is a humble transmigrator, a miracle doctor who doesn’t care for the many handsome men around her. She only wants to become strong, to be worthy of that god-like man. But when she’s finally sure of her feelings, she finds out she’s already been married for years…
……
When wronged：
She uses strength to hit the big handsome iceberg-like man in front of her eyes. “People say that I’m not good enough for you, but it is you who is an old cow eating tender grass!”
A man seizes the main point and laughs like an evildoer. “This husband has to eat the grass to confirm if it is tender or not!” He puts out the red candle……
……
The world says：
The barbarian king has no heart and has no passion.
A pregnant woman very miserably thinks,” If he has no passion, then who is responsible for this big belly?”

“You want to steal my genes then leave?” He grabbed her and tried to force her to hand over the child that was born three years ago.

Beatrice Da Ville was supposed to be the villainess. A spoiled, arrogant noblewoman who terrorized the heroine, only to be executed for her crimes. At least, that’s how the story was supposed to go.But when a 21st-century woman wakes up in Beatrice’s body, she has zero intention of following the original plot. Execution? Betrayal? A bloody downfall? Absolutely not. She just wants to keep her head down, avoid drama, and live a long, peaceful life.Unfortunately, her unbothered attitude, modern slang, and sheer survival instincts keep catching the attention of all the wrong people. The nobles think she’s a genius, the royal family is amused, and worst of all—the cold Crown Prince Francois Montague, who was supposed to fall for the heroine, won’t stop watching her.Meanwhile, the original heroine, Johanna Lockhart, starts to realize that her perfect fairytale is slipping away. The world that once adored her now whispers about Beatrice instead. And the more she loses, the more dangerous she becomes.With a fate that refuses to let her go, a jealous heroine turning villainous, and an infuriatingly handsome prince who definitely didn’t love her in the original story, Beatrice has one goal.Survive. Thrive. And absolutely, under no circumstances, follow the script.

There’s a legendary Bishoujo Game that has become popular among Japanese gentlemen.
