Fallen Leaf Turned Loner

Luo Tiantian sacrifices herself to save Bai Yueguang, only to wake up in the novel her best friend had written as a prank.
The best friend of the original owner of this body has gotten plastic surgery to take her place, snatching everything she had. She has even been imprisoned for ten years!
To avoid a tragic end, Luo Tiantian clings on to the greatest boss in the novel. 
After she shoots to fame overnight, the internet is teeming with curses toward her, claiming how she had undergone plastic surgery, was one to put on airs, and was being kept as a mistress…
She doesn’t even have any time to respond before the female lead’s lackeys suddenly change their stances.
Her eldest brother, a CEO: “She has the Luo Corporation backing her. Miss Luo doesn’t need a sugar daddy.”
Luo Tiantian’s expression darkens. “Scram! Don’t provoke me!”
Her second brother, a forensic pathologist: “As someone working in forensics, I can confirm that my younger sister is a natural beauty. She’s never had any plastic surgery done.”
Luo Tiantian sneered. “Who are you?”
The movie star: “Tiantian, you’re my fiancée. How could you live with another man?”
Luo Tiantian stares at that stupid face. “You?”
-
The moment she returns home, Luo Tiantian tones down immediately. 
Her boss glances at Luo Tiantian with what seems like a smile. “An orphan?”
Luo Tiantian nods innocently. “Yes, my entire family’s dead. I’m the only one left.”
Her boss raises his eyebrow. “A fiancé?”
Luo Tiantian quickly shakes her head. “No, no. That’s nothing more than a rumor. You’re the only one in my heart!”
-
From then on, the big boss undergoes a drastic change and becomes henpecked. He gazes at her affectionately. “Little friend, you’re toxic, but you’re my antidote.”

Business Tycoon vs. Drama Queen Star

"Alright, remember what you said."

Xue Feijing gritted her teeth as she glared at Luo Tiantian.

"That won't do. Sister Jing, you said that you'd make me famous." Luo Tiantian shook her head and replied innocently.

Xue Feijing flew into a rage because of her innocent expression. She roared, "Ask your uncle to support you!"

Luo Tiantian lowered her head dejectedly and her shoulders sunk. She seemed to be on the verge of tears.

Xue Feijing frowned, realizing that she might have frightened the kid.

Just as she was about to say something, she saw the kid whip out her phone.

A few seconds later, she heard, "Uncle, Sister Jing doesn't want me anymore."

Xue Feijing's expression darkened. "Luo Tiantian, it'll be a pity if you don't become a movie queen!"

Luo Tiantian's tears turned into a smile. "Uncle, Sister Jing said she'll make me a movie queen!"
