People like her don't need anyone to warn them specifically; she knows exactly what he does.
She doesn't dare to defy him in the slightest, fearing that if she offends him, he might kill her in a fit of displeasure.
As for Ye Ranran's invitation, she's torn between wanting to refuse and not daring to because One has returned. If she were to dine with Ye Ranran, she'd inevitably have to face him.
To her, this is nothing short of torment.
Now, hearing his words, she flees as if granted a special pardon.
Watching her flee in panic, Ye Ranran smiles at One, "What did you do to her?"
One, full of exasperation, responds, "Nothing. What could I do to her?"
Just with that face of hers, it's impossible for him to harm her.
"Then why is she so scared of you?"
What was originally meant as a teasing jab surprisingly receives a serious answer from One after some thought, "I guess it's because I have a certain authority."
This statement makes Ye Ranran laugh.
