Mrs. Sinclair doesn't like her, holding prejudices against her while blindly trusting whatever Cecilia Lynch says.
No matter what Cecilia says, she believes it, not realizing that Cecilia has been using her like a fool all along.
Bella Acker didn't initially want to speak to Mrs. Sinclair that way, but her current mood is really not good, and facing such questioning from Mrs. Sinclair inevitably ignites her anger.
Ms. Young was right; some people are destined never to like you. In that case, there's no need to lower yourself and humble yourself to please them.
As long as everyone minds their own business, it's fine.
Mrs. Sinclair's face darkened further after hearing Bella's words, "I will naturally ask the necessary questions; I don't need your reminder, Ms. Acker. However, I do want to remind you, as long as I'm alive, I won't watch you walk into The Sinclair Family's door, so you'd better abandon those crooked thoughts."
