"Abused and disowned by her family after she was found heavily pregnant, Ji Weixi was forced to leave her hometown with nothing to her name.  She returns four years later, only to be caught in a job with Li Shaoling, her stepsister's fiancé-to-be as her boss.

Ji Weixi was holding up a certain body part of the child and aiming it at the toilet.
The tot's brow eased amidst the gushing. "Comfy…"
Li Shaoling's gaze was overwhelmingly icy. "You are not allowed to touch him there!"
Ji Weixi stared at him as if she was staring at an idiot. "By what right?"
Li Shaoling glared at her. 
"You are only allowed to look at mine."
"Never!!!"

Mister Li, the Heart Bandit

"You'll see if I dare if you die!"

"Aren't you afraid I become a vengeful spirit and make you a widow on the day of your wedding?"

"Those things are female. You're so stupid."

Ji Wei glared at him, utterly exasperated. "A big man committing suicide just because of a little setback. How embarrassing!"

Li Shaoling was speechless again, but this time he glared hatefully at the little one, who spread his arms innocently.

"I was just telling the truth, Daddy. You looked so hurt it looked like you're trying to kill yourself. Tsk tsk tsk."

Fine. No painkillers now, and Ji Weixi was actually disgusted with him.

Still, Li Shaoling decided to beat her at their own game. "Ji Weixi, you could tell that I only have feelings for you. I'll die if you don't marry me."

The word 'die' seemed to especially unacceptable and frightening for Ji Weixi. "Don't try to force me, Li Shaoling."
